Agree with rampage and other posters that this play is not at all about AD "forklifting" Zack into his QB.
AD has made some of the most amazing plays I've ever seen in my life. But this ain't one of them. The twitter post is very misleading.
AO is a big guy who takes 5 or 6 yards to gather up a head of steam before slamming into AD and Zach, helping to push both of them back into the QB. IMHO, there is no way Zack completely collapses like that without AO helping with the push.
There's plenty of tape to make the case for AD's transcendent talent. And I'm sympathetic to jemach and others who would argue that a once-in-a-generation talent is worth paying an extremely high price.
It's just that this PARTICULAR play is not a good example of that.
