You can expect 12-17 skillpops a season. I had a guard 6.0 heigh he poped 16 times when was 19 years old and every season atleast 10 pops, age 22 now and already poped 5 times this season:) All this with 4-5 lvl trainers. Also i have to mention that 6.4 guard is struggling alot compared to 6.0 one 3-4 pops less each season, they were getting identical training weeks.
