I think Al Jefferson is going to get better than him.
For Curry to stop that he needs to play MUCH better Defense with a little effort.
The fat f#ck is so lazy - he can be a real defensive beast with his size and athleticism...but until Isiah demands him to play D and benches him like he did Marbury, Jefferies, Nate etc. for lack of it - he will not want to get better at it...
However, I wouldn't trade him. With Agguire as a coach, I am sure he can work wonders with Curry in the offseason, learning positioning, better passing out of the double teams, better floor spacing and understanding how to block out and rebound.
He is still young and can be great - if only he pushes himself to want that.
