IMO, owners are responsible for doing their homework prior to offering, or accepting a deal. I generally have the "a card laid is a card played" philosophy.I was contacted by 2 owners in my league who made a deal last night.At 6:30 pm last night Team A offers: Peyton Manning, Cedric Benson and Steve SmithTeam B would give up: Derek Anderson, Larry Johnson and Greg JenningsTeam B accepts this trade offer around 10 pm last night.Team A emails Team B (and me) this morning saying he wasn't aware of LJ's injury status and he wants the trade cancelled.Considering he proposed the deal on a Tuesday, he really doesn't have a leg to stand on, does he? FWIW - Team B has told me, privately, that if the other owner "babies it up" that I can cancel the trade, but that his preference would be for it to go through.Thoughts?
