The lineup I'd like more is:
Tyreke
T-Will
Acquired SF (Batum in free agency, a trade using Jimmer, Hayes, Garcia's expiring etc?)
Robinson
Cousins
That creates a bench containing an explosive scoring sixth man in Thornton, an experienced role playing PF/C in Thompson (if he's resigned), a change of pace PG in Thomas, a project weakside defender/shotblocker in Whiteside, a mediocre long SF/stretch PF in Outlaw and other filler.
More importantly it creates an absolutely brusing starting lineup that will run the floor, attack the basket relentlessly in transition AND in the halfcourt, defend well, and dominate the glass. Not ideal in a few ways but certainly a mismtach for most teams (on both ends) and certainly competitive.
