An Example.
Leon Arana was the 7th Pick in the MFN-7 2023 Draft, my very first Pick. He was a TE. I tried adjusting the Play Book so he was the main focusing, and just couldn't tweak it. Gave up on Passing, moved him to RB.
He's at 87 on Positional Experience, he got there in 5 Games at the Position.
He has, by the end of his Rookie Season (Missed Play Offs, so we're done this Year), 27 Offensive Plays that are at 95%+ Mastery from what I can see by the bar. Either no space seen or a slight sliver.
But he doesn't have ANY Defensive Plays over 40%.
So for me, the real impact is he needs 13% more at Positional Experience to get where he needs to be, and he'll only continue to add Offensive Plays to his Mastery to be good in. If I rotate (I have 2 other RBs, so shouldn't be an Issue) then Fatigue shouldn't be a Factor.
So he's only missing 15% of being a Super Saiyan, but it looks like either 2 1/2 Seasons for the most regular Plays before he can get there at the shortest time frame.
