I know he played well, but it's not good for Mitchell to play 40 minutes, not even 35 minutes. Let's remember what happened to Grady (plantar fascitis) playing that much. And it's not like that game was ever tight.
He definitely has improved his rebounding the past 4 games (11.75/gm)! Before that he was actually rebounding bad, with his numbers down around where the guards were. On the season, even after past 4 games he is still 4th in rebounding rate (Reb-per-30min):He knows how to rebound. The team needs to help him with that.
