Ignore the last few weeks of his training, my initial concern was why driving didn't pop after 1 week of One on One. Before I bought him he'd played every game of his career at PG, about 20 weeks worth. He had 12OD so I'll assume training was left on pressure the whole time, probably two position or with a low level trainer. Pressure trains some driving, I don't know the exact figures. With a high driving sub level plus the elastic effect I was certain he would pop.
I trained One on One the first week because I had an extra trainee, haven't trained it since.
