I have been beating this drum since the beginning of last year, but no one is listening. I will try again though.
Zeller looked like Bennett his first year. He was outclassed and out muscled. In the offseason he put on 15 lbs of muscle and came back playing like a man. I saw it in his very very limited minutes while Bynum was around. He would regularly put up a point per minute mostly off transition buckets. People started coming around on him later in the season as he got more playing time. He has improved a lot defensively, and he is our best offensive big including Hawes IMO due to his speed and divers game(shooting + post game). So what the problem? He has not been used correctly at all.
Zeller is a mismatch for opposing centers. He has the game of stretch 4, so he can pull rim protectors out of the paint, but he also has a good post game and he is 7 feet tall. He can roll to the basket and finish better than Tristan, and probably has a better handle too as he has shown the ability to go around guys. He often doesn't need that because he is an awesome mid range shooter. That 12-15 foot shot was automatic last year.
This guy regularly beats everyone down the floor. He can really get out in transition and then finish. He has fast feet like Andy but with quick ups to actually dunk the ball. He is much more athletic than given credit for. So what are his weaknesses?
IMO he has 1 major weakness, and 1 that should be easily correctable. He should be getting more rebounds at his size. He doesn't plant himself well enough aso he gets bumped off his spot for rebounds all the time. He has been working on his lower body, so that should help a little. The other minor issue that I see is his screen setting. His timing with the guards is off so that he is called for moving screen all the time. I'd blame it on the guards, but I actually think it is because he sort of "jumps" into position. He does a little hop to set himself and so when he sets the screen he looks like he is moving more than than most guys. He needs to be more low profile and set himself quicker.
Seriously, Blatt said he like to exploit mismatches. I will be heartbroken and shocked if I don't see Blatt get these guys to pass the ball ahead and get it to Zeller on the run. No one could do that last year. We could easily improve scoring by 6 or more a game just by getting it ahead and allowing him to dunk it, or go against a potentially smaller opponent in the post in transition. Once the opposing center is glued to Zeller, it is a field day for Dion, Kyrie, and our own baby Wiggins.
Zeller isn't Embiid. He doesn't have the wingspan or raw talent. He does have a very solid understanding of basketball and lots of experience. His trial by fire his rookie year led to him looking much better and stronger and more confident last year. He can be our starting center going forward because of the threats at other positions and because of his skills that create a mismatch on the other end.
Plus he is our best shot blocker, and his ability to draw O fouls lead to the same result except in that case the Cavs always get to keep the ball.
