You mean exhibition matches? You should play Leagues and Tournaments, you get prizes for those, and your players get EXP, so they become better. ;) The only real reasons to play Exhibition matches are:
1) Practice (obviously)
2) You waste your time trying to learn techniques rather than having to focus on actually winning the match. lol
