To me we'll see a combination of:
The last guard spot will be dependant on matchup for that game. If we're playing team with a bigger guard you'll likely see Cheatham.
To caveat, you'll likely see all 4 on the floor to close the game
Curtis probably spots Mack's minutes at PG also.
Up front my gut tells me it'll be:
If Cross elevates his play and adjusts quickly you could see him plugged in for big minutes.
Kavas will likely be one of the first guy's off the bench.
We'll likely find out more during the Italy trip.
There's versatility with this team. Having options is not usually a bad thing.
