I have no idea why we're moving Rivers for a 2nd rounder and expirings. Rivers is expiring and it's in our interest to put him in games. Either he'll play himself out of the league (and us further in to the lottery) or he'll get comfortable with our system and resign here to prove himself.
I can only assume the Pelicans thoroughly searched for a market for Rivers and came up dry. We should hold on to him to see if he develops here. We have so many 2nd round picks it's starting to become comical (11 over 5 years, possibly more).
I think with the right coach Rivers might be a decent pro. I wasn't ever high on him and I was against trading up to get him in 2012 (really wanted Harrison Barnes) but I'd let him have Thornton's minutes. He and Smart might fit well together. They have somewhat complimentary skill sets and they're both still very young (20 and 22, respectively).
