the spurs paid murray coming off a torn ACL because he showed what he could be. even if jeremy was completely healthy, with the body of evidence we have about his play, he wouldnt be extension worthy.
the caveat is if he was healthy enough to play in eurobasket and really balled out there and showed something new, and continued that in camp/preseason... there'd be a conversation. but im not a big believer that in the 2 offseason months prior to eurobasket he developed his game more than he has in the past 3 years
