Rockets also got Harden and he is already a ball heavy handler along with Lin. Not sure if Rondo could play with Harden, it might just hinder him.
Not sure the Pacers would would mess with their line-up too. Hill is a good PG and back-up Watson is good in that bench role. They are doing well and making that big change might just screw the chemistry up.
These 3 teams has to really mess up badly and have terrible records (as in not even going to make the playoffs) by the trade deadline to even consider trading one of their big asset players for Rondo. Nuggets might be able to trade away Lawson to get Rondo, that one could make sense. The other teams, they seem better off w/o Rondo.
