Hi, If those scouts did what are their own challenges,it already would be a good thing.

Beyond special ability (usefull or useless), I've often had highly-quality-rated scouts always having
low performances, for example aereal defenders /dmc conceding goal on corners,or defensive walls
conceding goal on 25 mts shots or free kicks.

For sure new training strategy allows you to improve required abilities of each player (while the old one
improved all abilities in parallel way).
Moreover ,after a certain period, those players maintaining their own faults and bad performance
though massive training strategy, should be eligible to go in sell list.

Training helps you understand which player is improvable (also considering different formations /orders),
and which is not.
