This is a very interesting comparison, thanks for starting the thread TMH. This will be great to watch over the next 4 years.
To add to the great research above, Muscala shot 46.2% as a frosh, Gabe was 52.1% and Tim is currently at 52.1% as well, although with more attempts per game.
One other interesting aspect to this is the way in which Kempton will have to improve. Muscala and Gabe were both pretty skinny, and I think more skilled than Tim. Tim has a bigger frame and can hold position much better at his young age. What Tim really needs to work on is explosiveness and quickness, whereas Gabe and Muscala mostly had to work on strength. One thing I love is that Tim has already shown a lot of improvement as far as determination and pursuing rebounds since the first game this year.
