I think that if he is trying to make this trade to achieve leverage later on, then it IS collusion. It just hasn't happened yet. Sounds like BS to me.
From what I read in the original post, this is what is EXPECTED to happen, not the reality of the situation. If I was the commish in this situation however I woud reject it to keep the integrity of the league in tact. Obviously the other owner has had a checkered past and at the end of the season the league needs to review his past and possibly get him and his dad out of the league. Your just going to be dealing with this yr in and yr out. Perhaps ask him the reason he wants to do this deal?
About the trade itself: Heath Miller is right now on fire. Perhaps he is a Pitt fan. 4 touchdowns in 5 games I believe? I dont see Crumpler putting up those kind of numbers. Glenn is a solid WR as well but has to contend for touches in that offense. Davis is also a solid back but that Houston offense is dreadful and defenses simply key in on Davis and limit his yards and have Carr beat them through the air. CJ, def a top 3 WR. I dont see the trade being overly unfair but considering his past, I would have to reject it personally.
All in all, I wouldnt even give him the chance to acheive leverage later on if that is truly what the commish is thinking will happen. Maintain the integrity of the league and dont allow him back next season. Good luck.
