btw, have you ever seen players who has 2 pops on 1 skill(afer 1 week of training)?
Just relating to the topic on a player going up 2 levels in one week - One of my centres went from inept to average in inside shot in 1 week. He had received 3 weeks in inside shot training with no success (22 mins, 21 mins, 46 mins) then popped after 55 mins.It hasn't happened since sadly.
