You want 48 minutes for a trainee ? Use 9 players in your order.
You want a good game shape ? Don't overplay your players.
first sentence comes with a price. you should agree. i did transitioned from three players at three games to one player as of primary trainee. in rare cases (when i can) i do this. but this game is not about training three players with 48 minutes in one position. you can not do that when you are at highest level of competition.
good game shape. that's another strategy. to buy 30-34 years old veterans. no staff. and in lbbl this strategy is not beaten yet. but i know, if not me, someone will beat it.
There is already many rules telling you how to play. Limiting tanking would be the same.
again. you can't beat tanking? why? tell me where you are loosing season after season to a tanker? show me :)
