If he doesn't want to move to 3rd what makes you think he'll agree to move to 2nd? And as ACTA stated in the other thread, he would cost too much and at his age I don't think it would be worth it. Also, let's keep this in mind about his new contract:
"no-trade protection 2007-09, limited no-trade protection from 2010 to May, 2011 (submits list of 8 clubs to which he'd accept trade), before receiving 10-and-5 rights in May, 2011"
Would the Nats be on that list of 8 clubs to which he'd accept a trade to? Of course he's asking for a trade so his demands may have to be changed. But I think with the Lerner's being so cheap this would be the biggest obstacle:
"09-13:$16M annually (total of $15M deferred)"
Maybe tomterp can merge this thread with the other one by NOTLD.
