I have to agree with 9erfan. If there is no collusion, then there should be no room to protest. Based on what I've seen here, there are "bad" trades all the time. For me, it's tought to make a call without seeing both rosters.
I happened to make a trade where I got A. Green for B. Westbrook and R. Wayne. You should have heard all of the screaming that went on. In that move, I was able to benefit from a team that had no receivers whatsoever due to injury. But, so far, who has the short end of the stick? Yep, me.
