I can't say for sure that any player should get a pop, bu I train 9 players, including 7 players 18-19 years old with high potential and low SS. For about year I have at least one pop in each teams and now I have no in any, so I thought that something is wrong. My players are young played 48 minutes in trained position, My trainers are rather good (5 and 6 level) so I think that is extremly unlikely to be happened.
