I would much rather have Thorburn and Peluso as 4th liners.
Thorburn is a serviceable fourth line player. If he plays as a fourth liner, I'm not all that concerned. Its not ideal, but I think its going to happen.
Peluso is not an NHL level hockey player, but it is unlikely that the 6 minutes a game he plays leads to THAT many loses.
Sure his presence means a better player can't have those 6 minutes, and the first 3 lines are going to have to play more, but I'm prepared for that to keep Pavs out of the net.
Pavs is a bad goalie. I think him playing 60 games instead of Helle or Hutch significantly hurts our chances of winning.
In the end, I think a bad goalie is worse for a team than a bad 4th line.
