I want to premise this by saying that I don't necessarily want him back, but I'm happy he's having success in Memphis. Not sure if you saw his latest stat line in a win against Indiana, but here they are:
Pts: 19
Reb: 11 (4 Off + 7 Def)
Ast: 6
Stl: 6
Blk: 1
Fgm/Fga: 7/14 shooting
+/-: +15
Now, that's a monster game! He's been having some great games since he's been inserted into the starting line-up. Although his overall stats don't look that impressive this year, much of that has to do with the fact that he hardly played at the beginning of the season. I don't think it's a coincidence that Memphis started playing really well after he became a starter.
