I am very anti-veto but I can see where the Commish is coming from. It seems a little fishy since you were influencing the other owner to make moves that you suspect he would not have done otherwise, in the process you harmed other teams that would have used their higher waiver priority on him. That being said, you must have had to offer him some value in return so it made his team better, which is generally the opposite result of collusion. I imagine that even if he didn't know about Cueto, after hearing how interested you were in him and maybe doing some research he should have been savvy enough to get some pretty decent value in return, right? If however he pretty much gave him away for free I think this situation seems a little fishy and should maybe have gone up to a league vote. Also maybe the league should consider changing it's rules or trying to replace the owner if they feel he is too ignorant for his own good / the competitive balance of the league.
