^^um,. he's already been offered his own team - several seasons back. Though it was done discreetly and the team didn't know about it. Obviously, he chose to stay with the team. Granted, he's a few years older, and the option may cause a different reaction at this stage in his career.
I do think he's regressed (as a character) the last couple of seasons from where he was toward the end of the previous Director's timeline, when he was initially offered a team. That was a mature, serious Tony then (well, as serious as the character can be).
