Telemachus
Starter
You failed to read my post. I talked about rebounding RATE. As you pointed out, he was rebounding at around 5 or 6 a game...in 15-20 minutes as a reserve, not the starter minutes of well over 30 that he's been with the Kings. So, again, his rebounding production in Houston was that of around 8-11 per 36 minutes, which is well over his production with the kings. He's actually grabbing less rebounds in way more minutes with the Kings than he was in Houston.
The problem with "rebounding rate" is that it is rarely accurate. It is much easier to play at high energy and go after every loose ball and rebound when you are playing 20 mins a game. When you know that you are going to play 35 mins a game, you have to pace yourself a lot more. There are a lot of players who can grab 4-5 rebounds in 15 minutes a game. However, you will be hard pressed to see one average 8-10 if they started averaging 30 mins a game. They would be more likely to grab 6-7. Rebounding becomes much harder with tired legs.
