^^ or thinking he can play well and hook up with a contender before the trade deadline?
I would imagine that he wants a ring more than anything at this point, but all the contending teams are already at or over the cap. Boston, Orlando, Cleveland and LA are all cap bound or over. They might do it, if they thought AI would put them over the top, that is make them a lock to win the finals.
Is he good enough to do that? Fit in with a Boston or LA well enough to make a difference? Replace Fisher with AI, or replace Rondo with him? Possible, but probably very remote. These teams already had a chance and did not pursue him, which suggests that they don't think he'd make enough of a difference.
