Just for the record.
I´ve three players with experience in 6, one in 9, one in 4 and two in 3, between them are mine 5 opening players and two first second choice player. I won incredible games against teams far superior... wich could be in part explained because of the experience, among other issues.
In mine case your example applies: i´m sentimental to mine trained players and i´m testing experience effect. (Just for this season)
