Why do players wait this long before retiring? It seems to screw over their team and is a sign of selfishness. Maybe he discussed this with the management before the draft and FA, but if so, they didn't prepare for it.
because he knows based on
the money they just sunk into freeney, leaving little else in the vaults
Giving up a first moving up to draft Ugoh,
the fact that (IIRC) they've already said they envision Ugoh as his successor
I'm guessing probably the numbers they've floated him in contract extension talksthat he is not part of this team's plans beyond this year. He feels used and either he honestly doesn't feel it's worth putting himself through the pain of camp and a season when he's so easily tossed aside and he figures he may as well screw them since they're already planning to do the same to him, or more likely he's using this as some sort of leverage in negotiations while he's still got some chips to play with.
