One of the big faults with YAHOO is they don't block players in pending transactions. It happened a couple times in our leagues years ago, before we all learned of the glitch. In our cases it was always accidental. A guy was trying to get an extra start in and YAHOO didn't really spell out that it would blow up a trade until it came as a suprise. You sound like he did this on purpose, knowing full well it would void the deal, are you certain? Maybe it was accidental and he'll redo the deal?

Cmon Bud NOW is the time to sack up and force feed an Olympic style drug testing program down Fehr's fat throat and save OUR game from these blatant cheaters!
