I'm a HUGE Rondo fan, but will be unbiased and say that Dwill is a better pg. He has more talent all around, and also doesn't have a jump shot problem, so that gives him a plus. But I will say that I don't think DWill would have helped us win the champ in 08.
What Rondo gives to the team, especially in 08, is so special, and unique.. What he does with the Big 3, and sharing the ball is something I don't see DWill being able to do. With three other superstars on his team.
I dunno, my opinion..
