I don't know bro...39 seconds in against the Jets I saw 2 I'd flag with this rule before I stopped watching. Tough debate and I guess we'll see how they 'tackle' it during implementation.
Edit: went back because I love watching Zach smash
so at about 1:25 against Faulk he does the weight drop and slight twist...these refs are going to get wild
then again...then again....they allowed Dbs to mug Hill and Waddle downfield past the bump-n-run allowance because.... according to one announcer who I forgot who it was... that mentioned how you can't cover them any other way so it needs to be allowed
