Probably which likely played a part in Kerr's departure. The message board "insiders" have indicated Sarver won't even pursue a possible S&T with Amare.
IMHO, ths sign and trade option is mostly a pipe dream. Anyone with the stuff worth making a sign and trade had the chance to make the offer in Feb. IIRC, the only trade offers were from teams more interested in his expiring contract. The teams with cap space had no interest in giving up stuff for somebody who would be outrageously expensive anyway.
This is not the JJ situation where the Suns could invoke their rights to match any offer. So it may be thatAmare is more attractive to good teams, but his knee is still more im;portant than not being able to afford him.
