Bertuzzi definately deserved to be on the team, but I think Spezza/Staal should be on the starting lineup, and Crosby should be one of the reserves at least.
I think you could drop Brad Richards, Rick Nash (he's been hurt all season!) and Shane Doan to free up those spots.
I guess they are going for experience over playing ability though, and Crosby will have plenty of chances to play for team Canada in the future.
