Were I a 5 star player, I'd be looking almost entirely at which program can get me playing on Sundays as a first rounder as a motivation.
Maybe if there is a virtual tie, some under the table money to my "uncle" would sway me. And of course when does the money change hands? A commit is a near nothing, and once you sign and are locked in, what is the payer revokes, you can't really sue him.
Maybe there is some half now and half later going on, dunno, if so I'd play the field, but I'm risking a lot of course, for a fraction of what my signing bonus would be.
