What? of course you get foul outs in this game. If you dont care about winning games then that training method would work.
But, in playing only 5 players per game you do run the risk of getting fouled out and "lucky fan" finishing the game. unless your remaining players are far better then the opposition you possibly could lose.
i have level 6 PR, i think its pretty important. it helps with merchandising and attendance. i would suggest just getting the best pr manager you can afford.
