Prior to this both Kadri and Wilson had been suspended 5 times.
Wilson however just got a $5k fine during the regular season for slamming the smaller helmetless Panarin to the ice and ending his season, while Kadri got 8 playoff games for his hit to the head.
Wilson's last suspension was 7 games just a few months ago in March of 2021. Which apparently didn't have any influence.
Kadri's last suspension was in 2019 for the rest of the playoff series, which ended up being 5 games. Before that, 4 games was his longest suspension. But they called him a repeat offender, even though by definition a repeat offender has to have been suspended less than 18 months ago.
