Nothing I've read indicates that EITHER contract is guaranteed. Guys don't come to camp without signing at least a non-guaranteed contract, do they? They've got to get paid while they're in camp.
A little surprised (and intrigued) by the Sweetney news. *IF* he's in shape, I remember him being a pretty good scorer down low (one of those guys that the New York media blew up into being a much better prospect than he was, but a good player nonetheless).
A little surprised that Bobby Swift wasn't the 16th man; he looked slow in summer league, maybe he just hasn't progressed. A little surprised as well that it wasn't a point guard, although it wouldn't be surprising to find out that Bobby Jackson got an invite and declined it (wanting guaranteed money) before they invited Sweetney in.
