I was wondering if other players have noticed if there have been a low amount of fouls, yellow and red cards. I have been playing on hard tackling and have 1 yellow card and no red cards for my entire team this season Didn't know if this needs to be adjusted, or if my team has just been really lucky this season.

if your players generally have low aggression, there should be less card.
if you're playing against a stronger side, your players tend to foul more.

OK, I am playing in the 3rd division against mostly bots, so that might be why I am getting less cards. Thanks

Depends a lot on how you play too.
S4-GDH in Netherlands division 1 already had 3 players suspended in the first 12 matches, one of them were suspended twice already and another yellow card will get him his third suspension of the season ;)

Dang, that's crazy. So yeah, it might be how I am playing and just a little bit of luck.
