1. Woody was a plus defender due to positioning and hard work. You're right his lack of foot speed did cause problems at times and his short arms and limited jumping weren't ideal.
2. MG and Sapp were both pretty solid perimeter defenders. That aspect will be missed. Offensively, I think they are both replaceable.
3. About JU I very much agree. I started noticing how much he was loafing on D, just about the time we started our free fall. He thought he could make up for it with his shot blocking but that is not always the case. Maybe he was thinking more about being an AA and going to the NBA.
Side note: Jok has improved his defense every year. Let's hope that continues this year.
It seems that the coaches have a lot more to work with this year to improve the teams defense, especially on the interior. Woody was the only real big guy with any kind of bulk last year. A lot of they guys they have now might be inexperienced, but they have some athletes with length and bulk.
