Here are some videos comparing Greg's performance before and after micro-fracture surgery in case some people want to see the changes that Greg underwent after the surgery. Before the surgery Greg's atheltic ability was stellar for a man his size. Here is a great site that shows his pre-draft physical, it also compares his OSU stats with last seasons numbers that he accumulated. In addition, it also calculates PER for both his NCAA stats as well as NBA.
I'm just hoping Greg gets back to that level of physique and conditioning once again. ::Fingers Cross::
