I haven't really seen it specifically announced anywhere, but on Spotrac, they have the Barlow contract listed as just a rest-of-season deal with him set to hit restricted free agency at the end of the season.

even with the spurs being over the cap, they still had the room exception to play around with, so the lack of long term deal is odd, unless PATFO, or more likely, barlow, doesnt want a bassie/champagnie type deal
if true, his QO over the summer will be just about 2 mil, which isnt much at all either way
