Rondo's trade value is now really, really low.
Teams trading for him have to look at him as not being available until the 2014-2015 season. (yes, I know there is a really good chance he will be back midway next season, but team have to look at worst case scenarios)
At that point, how many years are left on the contract? One player option.
So which "lotto" team in their right mind is going to trade for Rondo who may only play one season for them in the future and give up something significant?
