Depends on the angle. Bankers from the elbow are harder to hit than straight on shots. However, if he is further over, I agree, he could use the glass a bit more...although I would prefer he just continues trying to get more consistent with the regular shots before moving on to bankers.
The guy I really wish would use the backboard more though is JO. Trying to swish those 8 foot jumpers is just so tough to consistently do. Someone needs to show him some tape on Tim Duncan.
Yes, I mean for him to take it from the 3/4 angles, straight on or even the elbows does not make sense. I decided to post this idea because I personally found it much easier to hit those side shots with glass, as the margin of error seems greater, and I can just "see" the target better (depth perception thing maybe). However, the turning point to post this came when I ran into an old buddy down in Florida last week, also life long Celtic fan, and as we were shooting around on a court, the first thing he said was "if Rondo would just use the backboard it would make him dangerous."
Right. Unfortunately, those 3/4 angle shots are not very prevalent. The way they defend him, he can get wide open shots from the top of the key, the elbow, or the corner. However, if he is over at that 3/4 angle, generally, the defense is much tighter, because that is the best spot to make the pass into the post from, plus, the angle makes it very easy for defenders to help from on both sides, allowing them to get up tight on him without really worrying of him blowing by.
Also, from the C's point of view, that 3/4 spot is tough, because it kills their spacing. It essentially allows one man to cover both that guy, and the guy in the corner, but if he is a couple steps further to the middle, it opens up the corner shot.
