Yes you do! In the first game I looked at, Forest-Villa, possession was 26:74 and fouls 6:9.
Only one player has the ball at any one time, so the other 9 outfield players are free to obstruct, trip, body check, pull the shirts of the opposition etc. Just think how many fouls are committed in...
There are quite a few comments on the BBC HYS about that 20% possession at home, but this one stood out:
'Strange that nobody hasn't commented on a glaring statistic in the game.
For a side that only had 20% of the play Everton committed 75% of the fouls!
And received 67% of the yellow cards!'
