Why are there so many people trying to find ways to cast this as a dive?
First, pretending that getting slashed on those unprotected tendons on the back of your leg is going to elicit any reaction other than falling over. Then doubling down and pretending he was slashed on the other leg, which makes zero sense.
Reeks of desperation to have the moral high ground on something. But at the end of the day, what Bertuzzi did is a (albeit minor) cheap shot and Marchand did literally nothing but react naturally to it.
