You jump ridiculously offsides ... then make sure you touch the football with your fingertips first before you go full speed shoulder into a kicker's leg.
Technically, you can claim they didnt blow the whistle so you didnt stop ... but any person not an asshole would have stopped.
Technically, you did manage to stretch out to get a fingertip on the ball while you committed 99% of the rest of your body into slamming into a kicker's leg.
Just an asshole move all around. Clear intent to injure. I wish these teams played again this year. Fuck Richard Sherman.
