I think it is so obvious, and I cannto believe that his agent supports this, but what TO is really trying to do, is be like in baseball a late seaosn trade just to get the ring. In baseball it happens all the time, in football it is not considered the norm. TO does not want to play a full season, nor does he want to go to training camp any more. He wants to get in on the last 6 games of a season, and then make run at a 3 game sweep in the playoffs. And he would help a team in that respect, and I am sure someone will take him to try and gurantee their chance to get a ring.
Many players have tried this before, but none make as much a spectacle trying. He is actually trying to say
" I am really tired of playing football"
