First off, I agree wholeheartedly with K in that Beckham is a total dumbass for doing it in the first place. And you almost can't fault the players (I have no idea how many) who took it when handed to them in the midst of that celebration. They probably thought it was a joke. Who knows? Having said that, there won't be squat that comes out of it. Worst thing will be give the cash back and hold your wrist out so we can slap it.
I do hope they hand deliver a back dated cease and desist letter to Odell, though.
