Mbah A Moute finished 18th of 81 in qualified PF's for DefRTG (shout to Bobby Gerould for the stat). That's a good vet signing. Of course, he's very injury prone, but he'll be just 29 when camp opens. He's still theoretically in his prime, if he can stay reasonably healthy. If's If's If's.
A no brainer at the veterans minimum, honestly. I'd wouldn't expect him to be part of the rotation when camp opens, but he'd be the 'next guy up', and due to his versatility, could fill multiple roles depending on goes down.
PG - Rondo, Collison, Stockton
SG - McLemore, Belinelli, Anderson
SF - Gay, Casspi, Butler
PF - Cousins, Mbah A Moute, Moreland
C - Koufos, Cauley-Stein
That's how I see this thing shaking out right now. A lot of versatility, so the depth chart will never perfectly indicate minutes played. I think Koufos, WCS, Cousins, Gay, Casspi, McLemore, Belinelli, Rondo, and Collison will make up the top-9, and be regular rotation players. If the Kings play 10 guys, Butler and LRMAM will probably swap that role throughout the season. We'll see if Moreland and / or Stockton stick.
