Even though I dislike Tate cause he is a hot-dogging d-bag, I am not sure he is a hypocrite. It sounds like Seattle wasn't that keen on keeping him, and once the Lions made the offer, he probably figured why not. Considering he's not even that good (but hell, I could catch 50 balls playing with Megatron drawing double and triple coverage all day), it is hard to blame him for accepting an offer that good.
As for Decker, what a dumbass. If he had gotten close to 10 mil a year, like was rumored he might get, then okay, but I gotta believe that other teams could have offered him just as much, yet he picks the Jets to go to? His career is dead in the water now.
