If he's not being stubborn, what's the problem then?
I know he is a young player, but it seems that some of the things he is inconsistent at, he shouldn't be. Take BBD for instance. While he does not always knock down the shot consistently (which is not unexpected of a young player), he AT LEAST takes the shot consistently. BBD never turns down an open shot because he knows what it does to the offense when the ball rotates to you when you're open and you don't take it.
This is what I'm talking about with Rondo. I don't expect him to knock down the open shot consistently, because he's still working on his shot, but there is no reason why he can't consistently take the open shot. BBD is about the same age, but with a year less experience and he's exhibiting a more willingness to do his job (sometimes doesn't always turn out good though). Turning down the open shot causes overpassing, shot clock violations, 3 second violations and a teammate having to take a desperation shot. He kills the offense when he does this.
Another thing I don't understand about his consistency is pushing the ball. He has games where he constantly walks the ball up the court against Doc's wishes. This is something he should be able to do consistently as well.
The rest I understand it's due to being a young player in the league. I just don't see any reason why he can't consistently attack on offense and take the open shot when it presents itself whether he makes it or not.
Rondo needs to talk to Big Baby about that.
Oh, this is not a bash on Rondo, I love the kid. Just some observations about his inconsistency that I don't understand.
