At this point, I'd say the only first string lock is Hall at PG, and maybe Fouss at C, but I could see Keita getting a chance. Recall that Fouss has years of starting experience and Keita has none, but we'll see.

Is this how it will play out? (no pecking order implied here)
Catchings vs Mag for PF
Saunders vs Demin vs Knell for SF
Baker vs Demin for SG

Obviously Crawford and Koz are developmental guys off the deeper bench barring some big surprises, with Trey as a scout team guy mainly.
