I know Jason Kidd was not a great shooter in his early days, but was he as bad as Rondo? And, at least Kidd could make free throws. I don't think I have ever seen a poorer shooting quality point guard in the 45-plus years I have been watching the NBA.
Mentioning point guards, there are a lot of good ones in the league. In my opinion, Westbrook has definitely passed by Rondo, and I really like the way Mike Conley plays. Bottom line: while I love the pass first, true point guard approach that Rondo takes, you really need a point guard that can handle a little more of the scoring load.
If Rondo's jump shot does not improve and if he does not take it to the hoop more rather than passing off when he has an open lane, he will not become a better player.
