No trade is exactly even, and everyone is going to have an opinion that one side got the better of it. I think having Deuce is the better option, but who knows? Maybe the guy trading Deuce has depth at RB and desparately needs a WR. Maybe he just thinks Wayne is the next stud at WR.
IMO, there are two reasons to veto:
(1) collusion, and
(2) unconsciounability, which means there is no collusion but the trade is so one-sided on its face that no sane person would make it and it threatens the competitve balance of the league.
In this case, I don't see any evidence of collusion, and this trade is not so terrible on its face that it should be vetoed.
Vengeance is mine.
