Kings should sign Reggie Evans, and re-sign Mo Evans. Here is how the starting five would look:
Bibby
Mo
Peja
Reggie
Brad
Reggie brings toughness, defense, and rebounding. Sure, he isn't much on offense, but there is plenty of it on the roster and starting five already.
Mo is more obvious. He has been in the system for a year, and surely in working on his game is his mid-range game, and probably ball-handling. He has little oppurtunity to start else where, Bobcats/Rockets, but that is very slim. Whenever he started or filled in (Mobley/Peja/DC) he made the most of it. Also showed many times his three pointer can be consistent. Yeah he could go to the spurs, but he'd be making less money, and be behind Ginobili on the bench. I think the Kings have the best chance to sign him out of the 3 or 4 other teams his agent said are interested. It'd go along with the Kings aspirations of adding and improving the teams defense and back-court.
How many players can be on the active roster/suited up?
