Boosting save percentage…

Last night on twitter I posted some GF%RelTM statistics which resulted in a number of comments but notably some from Stephen Burtch about how players cannot be blamed for GF% and is nothing more than a fancy +/- stat and how players can’t be blamed or given credit for things such as save percentage. @hockeyanalysis @mlse Polak .910 on-ice sv% at 5v5 close past 4 years. Robidas .905 on-ice sv%. We should totally blame them. — Stephen Burtch (@SteveBurtch) September 26, 2014 .@hockeyanalysis @mlse Carl Gunnarsson had a .926 5v5 close on-ice sv% which was totally caused by his skill.

TSN Analytics Team, Even Strength Play and Marc-Edouard Vlasic

Earlier this week TSN announced the creation of an Analytics team consisting of long-time TSN contributor Scott Cullen along with new TSN additions of Globe and Mail’s James Mirtle and hockey blogger Travis Yost. I am all for main stream media jumping on board with hockey analytics but once you go from independent hockey blogger to a significant contributor to TSN I think it opens the door to higher expectations and higher standards.  Scott Cullen has a long track record with TSN and I am confident James Mirtle will bring some intelligent insight as we are all familar with and respect his
