O'Quinn will most likely get more than 16 mins. He's a more efficient player and will be more productive than some others we have, so I can see him deserving more minutes.
The big question is what we will get from KP and Jerian. If those 2 can adjust to the NBA level and have some decent production, then it should be a good year. Those 2 are the X Factors IMO. They don't have to be World Beaters, but if they can be solid contributors it will help a lot to round out the top of rotation.
I agree with dk7th starting lineup:
grant 28 minutes
afflalo 32 minutes
melo 32 minutes
kris 24 minutes
lopez 32 minutes
I think KP will be in better shape by the time we're playing regular season games. He was not in prime NBA shape in SL. He's got a few months to build up his nutrition, conditioning and strength.
