what lvl trainer are you using?
I have a level 5 trainer and I have been doing one position training all year.. including the all-star break and now the playoffs. 
My other 18 yr old draftee from last year is getting the same treatment, but only has 10 pops so far with a good chance at two more before the age switch. 
No injuries help my cause as well.
