I supposed you could just tell him that he can't play period, won't really hurt anything. I'm just saying that he already played 11 minutes a game at Duke without any injury or issues and did fine. He may not have played well, but that's a different issue. I don't see why he can't continue to play 10 minutes a game, that's also part of his training. It's called specificity of training. If you want to be good in basketball, you practice basketball related activities. It's why I always have thought that practicing anything else is dumb. Players in the past have practiced boxing (Boogie, Ben) and I always wondered who told them to do that. Does not help them become a better basketball player whatsoever.
There are a ton of variables in play when setting up an exercise or training regimen for someone. First, you have to decide what you are trying to accomplish. Is it strength, endurance, or power? Each of these will lead you down a different path. Once you have chosen your avenue, you begin your training. My guess is that the training staff picks strength, as it combines endurance and power.
Structurally, his knees are intact right now and technically he can play and has already played. My guess is he will play at some point this year, but will receive a ton of attention off the court. The goal is to strengthen the muscles around the knee in order for muscles to absorb as much force as possible and sparing the knee joint itself. However, as someone pointed out in that article, his were contact injuries. It wasn't caused by weakness. That's why it's unlikely that he sits out the entire season.
