Hi guys- I got around to youtubing a lot of Upshaw videos and the thing that jumped out at me the most was the type of position defense that he plays. He stands in the paint, doing nothing in particular, until someone drives the lane. He seems to have great timing as a blocker, it's true, but this is the same sort of center-fielding that made Fab Melo look so great.
The zone shot blocker seems to me kind of like the NBA version of the system quarterback. I'd definitely use a later pick on someone who has demonstrated this kind of shot blocking skill, but in the first round I'd be pretty scared to.
