PA-PLAYA Hurts’ ability to squat 600 pounds has a lot to do with their success with the QB sneak.
Even as successful as the Eagles have been with that play, I have wondered if it might be even more effective if they went all-out for size and strength - have Barkley or Goedert take the snap, with either backup offensive linemen or some of the big guys from the defensive line (Jalen Carter/Jordan Davis?) providing the push from behind...
At the same time, there probably is a case to be made for banning the play for health and safety reasons - it's effectively a rugby scrum without the 'touch/pause/engage' sequence to slow down the initial impact (and there have been too many life-altering injuries (mostly neck injuries leading to paralysis/limited mobility) to rugby players as a result of scrums gone wrong for anyone to be able to claim with certainty that there is no risk to that type of play.)
