Is Scott Boras extension adverse, yes but there is a good number of his players that have signed extensions before, usually because the player likes his current team and situation(Weaver, Madsen, Andrus). If he'd truly be crushed to leave a deal would get done I have no doubt. As far as trade value goes, Carl Pavano strikes me as a player with a similar situation and results. That netted the Indians a C/borderline C+ prospect who had excellent stats but underwhelming stuff(Yohan Pino). Value in that trade was probably slightly reduced due to it being a waiver trade, cutting the suitors down to 1.
