There were 60 red cards in the league last year, or 2.5 per team. So having 5 called against your opponents is probably on the high side.
Still, some of that is likely because we were a good team that other clubs struggled to defend. Just like in basketball where the better teams tend to get fouled more often.
And besides, if you take the 13 points and 5 games out of our results, our points per game drops from 1.88 to 1.76. You know what 1.76 PPG got you last year? Second place in the league and first place in the East.
Also, we only suffered one red card last season. Anyone remember who?
