More like least impressive defense in NFL history. At least 5 people should have been positioned to attempt a tackle, but only 3 actually engaged him, and they looked like they were playing in the Pro Bowl.
You're not going to dive if you're keeping pace and can grab him directly because you have more leverage and options. A dive is if you're unable to catch or may not reach otherwise. Of course, you're then supposed to not get flung on the floor like a little diaper baby.
Beast mode is amazing because the tackle attempts were all top tier. Marshawn just wanted it that day and everything went right. I'm not diminishing the OP but beast mode is even well regarded by rational Patriots fans.
Beast mode is a legit contender for GOAT running plays and should at least be in everyone's top ten.
