Not sure if you or RF saw this, but I really felt that, in the last 15 games of the season, he was making the most of his minutes and really contributing. Most of it was using his body better -- guy is really massive out there, even at a "svelt" 250+. His strength is back, and when he sets his mind to it, he can just clear people out of the lane.
This season, I'm hoping his low-post OFFENSE returns. He hasn't had rehab to slow him down. He's healthy, he's strong, his weight is good. I think his wind is better after last year's FF run. Now let's see if:
1. He can start getting getting better position. On D, instead of silly arm-rakes, he needs to establish position and take some charges. This is perfect for him, since he's not an above-the-rim eraser.
2. On O, as I said b/f, I want to see that low block offense we know he has in his tool box. The baby hook, the drop step, the elbow jumper .. maybe even an up and under move. My guess is he's working with Hop on this as we speak.
