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.

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.

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.

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.

Now, after a stunning run in Melbourne, Stanislas Wawrinka has a new nickname: The Stanimal — a tribute to his gritty, fight-until-the end style of tennis. Fittingly, perhaps, the name was apparently coined by none other than Roger Federer, in a tweet of support for his friend which quickly caught on earlier in the tournament. Now that Federer is out of the running — he lost to Nadal in the semifinals — the 17-time Grand Slam winner and long-time ambassador for Swiss tennis has joined those cheering for Wawrinka to win his first Grand Slam final. It is a match that holds historical significance for all three players. If the No. 1-ranked Nadal wins, as the odds suggest he will, the 27-year-old Spaniard will become the first player to win each of the majors twice in the Open era. It would be his 14th Grand Slam trophy and bring him one step closer to Federers all-time record of 17. If No. 8-ranked Wawrinka beats Nadal to win his first major title, he catapults to a career high of No. 3 in the rankings. Just reaching the final assures Wawrinka of the No. 5 spot, meaning for the first time he will pass Federer, who is now ranked sixth. On the eve of the final, Wawrinka said he was still shocked by his success. "Its insane. Its incredible," the 28-year-old Wawrinka said Saturday, speaking to reporters in English and in his native French. "I never imagined that one day I would be here, playing in the final." After a breakthrough year in 2013, Wawrinka is playing the best tennis of his life in Melbourne. He knocked out three-time Australian Open champion Novak Djokovic inn the quarterfinals and beat No.dddddddddddd 7 Tomas Berdych in the semifinals. He knows how tough it will be to beat Nadal — hes tried and failed 12 times. "Ive played him so many times, and lost so many times, but Im going to try again," Wawrinka said. "I know what I have to do. I know that I have to play aggressive, serve really well, and try to always push him." "Im playing my best tennis here," Wawrinka added. "Physically, Im ready.". Nadal says hes ready, too, for a breakthrough at what he calls his unluckiest Grand Slam. Nadal won in Melbourne in 2009 but in subsequent years struggled with injuries during or before the seasons first major. He missed the 2013 Australian Open during a seven-month layoff for illness and a knee injury. He returned to win the French and U.S. Open last year but reaching the final in Melbourne holds special significance. "After missing last year for me its really, really emotional to be back on this court, Rod Laver Arena, and to be able to play another final," said Nadal, who has known Wawrinka since they were teens, playing junior tournaments in Europe. "Hes a good friend, a great guy. Im so happy for him that hes in the final. He deserves it," Nadal said. "I know it will be a very, very tough match." Wawrinkas other longtime friend, Federer, had hoped Sundays story would be about an all-Swiss final. But after losing the latest installment of the Federer-Nadal rivalry, hes cheering for Wawrinka. "I hope he wins, and I hope he gives everything he has," Federer said. "Theres no reason not believe that he can beat Rafa." "Stans in his first Grand Slam final, so that makes Stan also unpredictable. Hes got to use that to his advantage."
