One of the common complaints hurled towards puck possession metrics like Corsi (ie. shot attempts) is that all shot attempts are not of equal value. When it comes to the individual level, clearly, there are differences in shot quality, as some players tend to shoot from closer distances, but when it comes to the team level, with thousands of shot attempts distributed across more than 20 players, it’s difficult to sustain dramatically different shot quality. Nevertheless, there is information to be gleaned by poking around with measures designed to pin down shot quality. Over at War on Ice, they have started using a set definition (involving shot location, whether it’s a rebound or not, or whether the shot comes off the rush) to track scoring chances, which could be a useful comparison and I’ve started comparing the scoring chance data with shot attempt data. The impetus for this comparison was noticing that Nashville Predators winger Colin Wilson was not only near the top of the league in Corsi%, but also best in the league in Scoring Chance%, so I thought there could be some interesting comparisons to be made, particularly at the top and bottom ends of the spectrum. First, the players with the highest percentage of scoring chances relative to shot attempts (minimum 200 shot attempts for) when they are on the ice for 5-on-5 play: SCORING CHANCES RELATIVE TO SHOT ATTEMPTS PLAYERS TEAMS POS. CORSI% SC% RATIO Brooks Laich Washington LW 50.8% 58.1% 1.144 Boone Jenner Columbus C 48.1% 53.6% 1.114 Eric Brewer Anaheim D 46.6% 51.5% 1.105 Eric Fehr Washington C/RW 51.5% 56.9% 1.105 Dan Boyle N.Y.

Then, the players with the lowest percentage of scoring chances relative to shot attempts (minimum 200 shot attempts for) when they are on the ice for 5-on-5 play: SCORING CHANCES RELATIVE TO SHOT ATTEMPTS PLAYER TEAM POS.

To that end, in the trailers list, comprised of largely lower depth chart players, its interesting to see players the calibre of David Backes and David Krejci. Turning attention to the elements, offensive and defensive, which players have the highest percentage of scoring chances among shot attempts? Of those with at least 200 shot attempts: SCORING CHANCES AS PERCENTAGE OF SHOT ATTEMPTS PLAYER TEAM POS. SCF SAF PCT.

Islanders D 313 575 54.4% Its no surprise to see Phil Kessel and James van Riemsdyk at the top, since both seem to generate a good proportion of their shots on rush attempts and they have enough skill to create quality chances, as does the trio of second-year forwards (Nikita Kucherov, Tyler Johnson, Ondrej Palat) in Tampa Bay or Jamie Benn and Tyler Seguin in Dallas. Of course, unheralded defencemen Adam Pardy and Thomas Hickey, as well as Islanders grinders Matt Martin and Cal Clutterbuck are on the list too, but this offers at least some indication that their respective teams are getting quality shot attempts with those players on the ice. And those on the ice for the lowest percentage of scoring chances compared to shot attempts. Again, minimum 200 shot attempts: SCORING CHANCES RELATIVE TO SHOT ATTEMPTS PLAYER TEAM POS. SCF SAF PCT.

Its one thing for Torontos top line to play firewagon hockey -- good chances both ways -- but it hurts to have their top defensive pairing giving up a proportionally high percentage of scoring chances relative to shot attempts which, against Toronto, is already a problem area. An important final point: We know the value of shot quantity metrics and how they apply to future results. None of these calculations are remotely all-encompassing measures that cover a player’s contribution, and without knowing sustainability and predictability, their long-term value may not be useful, but – in this moment – they can help add some context to more widely-known possession stats. Theres likely more to be discovered here, but adding some measure of quality ought to help in player evaluation. From Monday night… HEROES Brent Burns – The Sharks defenceman had a goal and an assist in a 3-2 win at Winnipeg. He ranks third in defence scoring, behind Mark Giordano and Kevin Shattenkirk, with 31 points (11 G, 20 A) in 40 games. Joe Pavelski and Logan Couture – Taking on additional burden with Joe Thornton injured, both played more than 22 minutes at Winnipeg and both contributed a pair of assists in the win. Pavelski also had game-best possession stats (17 shot attempts for, 8 against, 68.0%). ZEROES Mathieu Perreault – The Jets forward has been productive after a slow start to the year, but he was locked down by the Sharks, failing to generate a shot attempt, tand taking a high-sticking double minor, while playing more than 18 minutes. LINEUP NEED TO KNOW Julien Brouillette – The Jets have provided a good opportunity to learn the names of lesser-known defencemen and Brouillette is the latest to get a turn on the injury-depleted Winnipeg blueline, with Grant Clitsome taken down by an upper-body injury. The 28-year-old played 9:33 against San Jose Monday, his 11th career NHL game (1 G, 1 A in 10 games for the Capitals last season). Much of the data included comes from www.war-on-ice.com.

Gauteng High Court Judge Dunstan Mlambo ruled Tuesday that South African media houses will be allowed to install three remote controlled cameras in court for the Olympic athletes trial starting next week to capture images that likely will be seen by millions around the world.PITTSBURGH -- New York Rangers forward Martin St. Louis spent Thursday night with his family in Montreal, grieving the loss of mother France after she died suddenly. When Rangers coach Alain Vigneault told St. Louis perhaps the veteran forward should remain at home rather than help the Rangers try to fend off elimination against the Pittsburgh Penguins, St. Louis and his father held a lengthy heart to heart. Hours later, St. Louis was in Pittsburgh. By the end of the night he was near tears after an impassioned team effort in a 5-1 victory that forced Game 6 in New York on Sunday -- Mothers Day. "Im glad were able to get this win and stay alive," St. Louis said. "She was a great lady, the best human being Ive ever known in my life. I owed it to her to do it. I know she would have wanted me to play." Buoyed by the return of their teammate, one who has fit in quickly after being acquired from Tampa Bay at the trade deadline, the Rangers shook off a lethargic loss in Game 4 by blitzing the Penguins early. Derick Brassard scored twice and Chris Kreider, Ryan McDonagh and Kevin Klein added their first goals of the post-season for New York while Henrik Lundqvist stopped 31 shots. St. Louis had one shot in 16:19 of ice time, all of it with his mother in his thoughts. "She was with me the whole way but this is probably the most comfortable place you can be as a hockey player," he said. The Rangers certainly looked at ease while the Penguins failed to win a close-out game for the sixth time in their last seven chances on home ice. Evgeni Malkin had his third goal of the series for Pittsburgh and Marc-Andre Fleury made 30 saves but lacked the crispness that allowed the Penguins to sweep Games 3 and 4 in New York. While Pittsburgh coach Dan Bylsma stressed the importance of not letting the Rangers back in the series, the fire he was looking for came from the other bench. Pittsburgh committed a pair of sloppy penalties the Rangers finally turned to goals and couldnt convert a lengthy 5-on-3 power play late in the second period as they tried to climb out of a three-goal deficit. "At the start I think we played like a team that looked like we had an automatic bid to the next round," Pittsburgh defenceman Rob Scuderi said. "When its 2-0 right off the bat and youre playing from behind its not easy." TThe Penguins held the Rangers to a 15 shots in Game 4, a franchise record for fewest shots allowed in a playoff game.dddddddddddd New York had 17 in the first period Friday night. Having its beleaguered power play finally look competent helped. The Rangers hadnt scored with the man advantage since Game 2 of the first round, an 0-for-36 stretch that often featured disinterested or disorganized play by New York whenever an opposing player skated to the penalty box. Kreider ended the miserable run 9:36 into the first period after Pittsburgh defenceman Robert Bortuzzo was called for delay of game for lazily flipping a puck over the boards in the Penguins zone despite having no pressure on him. Playing in his second game after missing more than a month with a hand injury, Kreider threaded a rebound from the bottom of the left circle in a small hole between Fleurys right pad and his blocker to give the Rangers their first lead in more than 180 minutes of play. Brassard made it 2-0 just over 5 minutes later, diving across the Pittsburgh crease to bang home Mats Zuccarellos rebound. The Penguins seemed to regain their swagger in the second period and Malkin cut the lead in half at the end of a thrilling burst in which he beat two Rangers to the net and did a 360- degree spin before slipping his own rebound by Lundqvist. The momentum didnt last. Brassard roofed a shot through a scrum in front of Fleury to make it 3-1 and McDonagh scored his first goal of the post-season with a shot through traffic from the point after Pittsburgh was whistled for too many man on the ice, the kind of untidy mistake the Penguins had avoided while winning three straight to take command of the series. Now its back to Madison Square for a series that suddenly looks competitive. "I dont think theres much good to take from it to be honest with you," Pittsburgh star Sidney Crosby said. "So I think we have to make sure we come with the right mindset going to New York. Whatever mindset we were tonight it wasnt enough." NOTES: The line of Brassard, Zuccarello and Benoit Pouliot combined for seven points (two goals, five assists). ... Pittsburgh forward Jussi Jokinens points streak ended at eight games. ... Pittsburgh scratched D Brooks Orpik, who appeared to suffer a lower-body injury in Game 4. ... The Rangers are 5 for 47 with the man advantage in the playoffs. ' ' '
