DJ was so different from Rondo, it really is not a good comparison. He was a big swing guard, not a pure PG like Rondo. He was a better shooter than Rondo. They both demonstrated great anticipation skills, seeing a play unfold before it happens, and that is why they both have so many steals. Rondo is much quicker than DJ was, but DJ had a deceptive quickness about him, and was extremely efficient with his movements, if that makes sense. I would say DJ was more of a cerebral player, especially with the Celtics, but that was due to being at the end of his career, where he had lost a step physically.
We as Celtic fans were very lucky to have them both.
RIP, DJ, you will get in the HOF.
Rondo, you are the present and the future. You will make the all star game this year, and for many years to come.
