From minute 37, the roster would be like this:
PG: Trainee 2
SG: SG 2
SF: SF 2
PF: PF2
C: C2
The problem is that Trainee 3 would get into the game at some point (for like 4 minutes) but Im not sure if he would go into the SF position or into the PG position.
Trainee 2 will get over 7 minutes at the PG position, which is good but Im not sure where Trainee 3 would go.
