I think you're underestimating just how much hand technique and leverage is involved in what linemen do. And grappling from stand up is about control and leverage.
But I'll gladly watch these wrestler vs. NFL lineman videos.
so what? Just because one aspect of their sport has similarities does not mean it will translate to fighting. We are not talking about bums here.
You seem to think just because they hold hands in an nfl game it somehow gives them an advantage in a fight vs a top ufc fighter.
you think it will be over if they grab them? What are they going to do when they get them to the ground?
Thats also ignoring the fact that they need to get close enough to hold them without getting kod. These guys train everyday not to get held/taken down by pros yet some random nfl lineman is going to easily take em to the ground and smack em lol
