Around the NFL Week 14

[CultBrennan59]

So I have a fantasy question for you all

I'm in an ESPN league where we have no waiver wire and our trade deadline has ended (our league manager didn't tell the league it was over we had to figure that out on our own). I have Roy Helu on my team, another guy has Cam Newton on his but also has Tom Brady. He doesn't have an RB. I wanted Newton but the deadline has passed. So he said he really needed an RB and that he would swap with me Helu for Newton. I would have to drop Helu late late at night and he would drop Newton at the same time. We swapped those players he and I were happy.

The league wasn't because they claim I 'cheated'. I see no way how this is cheating if two teams agree to swap players and if that's cheating than any other player that has been added and dropped by a team from another team should then be cheating. Is this cheating?
