NHL Combine news (updated)
"Jonathan Toews struggled in the anaerobic portion of the physical testing. The North Dakota forward threw up after his stint on the stationary bike and his bench press was well below median. But as stressed earlier by Central Scouting, the physical test is only one component. Anyone who has seen Toews on the ice (with the Fighting Sioux and the 2006 Canadian World Junior team) knows his potential as a top three selection."
Earlier in the story, Central Scouting director E.J. McGuire is quoted as saying there is a push to add an on-ice component to the combine, which it currently lacks. "The physical testing doesn't affect a player's draft ranking. It gives teams a look at how he looks and how he may look in a couple of seasons," McGuire told TSN.
Update: TSN reported that stationary bike handed Minnesota forward Phil Kessel the same fate as Toews. Speculation is that the NCAA players have fared worse in the endurance testing because their season has been over for two months now. Some other prospects played into late May. As McGuire said, this shouldn't affect the draft status of either Toews or Kessel, who are likely top five picks.
