The effect of the NHL lockout was evident at the intrasquad game.

While the lockout has made some of coach Steve Spott's decisions about forwards and defencemen simpler because he has the country's best talent available to him, goaltending is an open race with no incumbent from a previous Canadian junior team.
Jake Paterson of the Saginaw Spirit started in net for White and stopped all 10 shots he faced, while Red counterpart Jordan Binnington of the Owen Sound Attack also had a shutout on just five shots.
Belleville Bulls goalie Malcom Subban allowed two goals on 16 shots in relief of Paterson. Laurent Brossoit of the Edmonton Oil Kings stopped 17 of 18 in his half a game.
Halifax Mooseheads forward Nathan McKinnon is one of two players at camp born in 1995. He played fearlessly and drew a reaction from the seats with his speed and quick moves around the net.
Spott said prior to the intrasquad game some players may be released Wednesday after a game against university players.
The Canadian team will be announced Thursday following a second game versus the university squad.
