I actually think it's more likely we see CV and Bouknight both starting (or at least getting the lion's share of minutes) at the 2 and 3.
I don't buy Polley getting significant time at the 3. I expect minutes to be distributed as follows:
1: Gilbert (30), Gaffney (10)
2: Vital (25), Bouknight (15)
3: Bouknight (15), Wilson (20), Adams (5)
4: Akok (20), Polley (20)
5: Carlton (30), Whaley (5), Akok (5)
Total minutes:
Gilbert - 30
Bouknight - 30
Carlton - 30
Vital - 25
Akok - 25
Wilson - 20
Polley - 20
Gaffney - 10
Whaley - 5
Adams - 5
It will probably be less equitable than that in big games or by the end of the season, but it will be somewhere in that ballpark barring big surprises.
