Looks like you guys are going out of your way to tie this to hextall when it's on both Berube and the medical staff.
Hextall is the one who decides who coaches the team and who is part of the medical staff. It's been obvious to any fan who follows the team well that Mason appears hurt for a while now. That's fans looking on from a distance, Hextall not only can know as much as he wants regarding the team (and should), but he has the power to change what he wants about the team.
Letting any player, let alone your starting goalie and only viable goalie in a clearly non-playoff season, trot out injured every game and practice is carelessness and idiocy beyond comprehension for what's supposed to be a premiere professional sports franchise. Leaving alone the fact that Hextall is supposed to be a man of vision and long-term planning.
