Only morons would say Cubes would take Rondo over Ellis.
Ellis is literally one of few guys that no one can shut down guarding him 1-on-1. He has impressed me quite a bit, as I was skeptical of their initial pick-up of him, but after seeing nearly every game he has played in as a Maverick, I have yet to see someone accomplish that, or even find a way to consistently stop him from getting off shots he is very comfortable with and can make with consistency. Now when you send timely doubles at him, he can struggle a bit more because of his size, but overall, for his size, he is as good of an offensive player as anyone else in the league. Add to it, he is highly clutch, doesn't get rattled mentally, and never gives up no matter what the situation is. He's a lot better than I had imagined him being (although I'm sure having Carlisle and Dirk helped him immensely), and really is one of the more underrated players in the league, even despite his inconsistent defense.
