dac, I use something similar to player roles ... the same concept of spliting up 100% in importance among the attributes by position. However, I also take into account Def_IQ, Off_IQ, and FreeThrows. Using my formulas, I would play this:
PG: Rule / Kowalkowski / Merrit / Tubbs
SG: Turner / Merritt / Tubbs / Kowalkowski
SF: Ramirez / Tubbs / Merritt / Kowalkowski
PF: Leyva / Tubbs / Hutsell / Burchfield
C: Colorado / Hutsell / Tubbs / Burchfield
Maybe put Crivello in one of the 4th slots for PF or C to get him playing time as well .. I would probably do it at PF. Same thing for the 4th spot for Briscoe at either PG or SG. I would probably use Brisco as the 4th PG instead of Tubbs.
Based on that chart (which is likely what I would use), I would say that the roles lineup is closer to what I would use than your eyeball lineup.
My other rule is that starters only play their position (and don't backup any place else), and the other players fill all 4 spots.
