First, get yourself a Vita Vea. Once you have a stalemate at the line, hope your athletic linebackers can make an athletic play.
In regard to your last paragraph. Teams have been watching Philly run this for a few years now so they’ve had ample opportunity to emulate it. That’s on them for not taking advantage.
Oddly, I’d push more to change the rule of say greater than 50% (just a figure) of the teams ran the play with the success rate equal to Philly’s cuz that would essentially render all 3&1’s and 4&1’s a leaguewide gimme. Now that would be boring. One team doing something special isn’t.
