I unfortunately haven't had time to be here much at all this past month -- and haven't been able to read this whole thread...
But, here is my take - sorry if someone else said it first...
Who the hell cares that he sat out a practice? I would rather him sit out every other day than going full on in each practice. He still needs to build more strength and get more confidence in the knee. Pushing it constantly is not the way to do that - and it is exactly what got him into trouble earlier in the summer.
Practice and training camp are important, but it is much more important to pace Amare so that he has a continual build of strength so by the end of the season he is in better form...
IMO, it is much better to keep Amare on a steady increasing workload. And I mean a long term deal, very long term - like all season.
He was rushed back last year and earlier this summer - so much so that it caused an issue in his other knee. It would be much better to see a slow but steady increase than to see good performance, then a setback...
Look at microfracture histories. The failed attempts (Webber, Penny), constantly rushed to come back, and when they did they came back hard. They had some great games, but always hit another setback.
Then look at the successful attempts (Randolph, Kidd). They slowly came back. They played most games, but weren't afraid to sit out every now and then to rest the knee. When they first came back, they didn't look bad - but they just weren't themselves. As time went on, and again - lots of time, they started to regain their previous form.
The goal for Amare should be to survive this season, and play in 85% of the games. To be a steady contributer, as a starter. To be able to post decent numbers, and help keep the defense honest inside.
Then we should aim for an All-Star player next season. Like I said, look at Kidd. He was an impact player his first year back, but nothing overly special. However, the following season - he was back in form. THAT is what we should be aiming for.
