I am guessing that all 3 pops were in different stats. I find it hard to believe that a 26 year old could pop that much unless each each of those stats were very close already
It was in three different skills (JR, HAND, DR). They were all really by accident becase this guy is not a trainee for me. I only played him in the training position because I needed him there to make my lineup work against some teams I could beat. Otherwise, this player would not get training minutes.
Also, two of the three pops he got were in skills that were super low, so they've probably gotten secondary training in past years that had those skills about to pop.
