Keeper League:
I'd be giving up Ray Ray and Derek Rose for Rondo and OJ Mayo.
I should note that there's also a limit on how long you could keep a player (absolute max: 4 years)
I'd say keep Ray & Rose
Mayo's going to shoot sub 40%. Rondo's not all that great a Fantasy player.
same, rondo's the fourth option on a team that doesn't care about stats, he's not going to produce fantasy stats as much as rose, who will be the focul point in chicago.
and ray is always good to score a ton, i would not do that trade, adn keep rose.
