This is a great tread. I decided to do this when I got a team, and my training for big men has been:
2 weeks of team stamina
1 week of team rebounding (2pops on trainees) lvl 6 trainer
C IS (2 pops)
C/PF rebounding (1 pop) switched to level 10 trainer
C/PF shot blocking (2 pops)
C/PF inside defense (3 pops)
C/PF inside shot (2 pops)
C/PF rebounding (4 pops plus 1 ID pop)
C/PF rebounding (4 pops)
To me, the ball is really rolling now with my level 10 trainer. I plan to switch to C/PF inside shot for the next two weeks because that's where I'm now weakest. If the 4-5 pops per week continue into next season, I'll be thrilled.
In the seven weeks of training, my best 19 yr old trainee has popped 6 times, always in the skill trained. My best 18 yr old got hurt for two weeks, but has managed 4 pops, including the week of his injury. His purchased trainee replacement popped 3 times.
All told, 25 pops on seven trainees in 7 weeks of C/PF training.
