Spezza is not on a hot streak, he was in a slump to start the season. He is a consistent point per game player and David Booth is probably Florida's best player. This is not a one sided trade at all. Yes Crosby is the best player in this deal but this trade is definitely not one-sided enough to demonstrate collusion or an attempt to dump bad players for good ones.
I agree that this probably solidifies Team B's depth for a run at a league win but not worthy of a veto.
