I'd go with the following.
PG-Westry
SG-Moore
SF-Bell
PF-Freeman
C-Lampkin
Carlos is not the answer, I'd start playing him as the backup PG we brought him in to be. Westry goes 6, sits 8 then 6 to finish for both halves. That is 24/16 breakdown.
Davis first up of the bench if we need scoring or one of our forwards is being defective on defense.
Freeman gets 8 of his minutes at the 5 when we are playing both other forwards or Taylor at the 3.
Spot minutes for Petar and or Play the big stiff 4min a game zone or press I don't care.
Lampkin has to be around 26 minutes or less if we want him to survive the season. Also his minutes should coincide with the minutes Carlos is on the bench. Let Lampkin facilitate offense as much as he can when Carlos isn't in.
Taylor is your defensive specialist situationally but he can only play if at least one of Moore and Bell are on the floor.
