I think running a 4-3 is viable given the Packers lineman. I am not sure they have the backers for it. Hawk is no MLB and I am not sure Jones is a Sam.
But put that aside for a minute. I haven't watched the film so it could have been some hybrid deal.
If your elephant is in the 9 gap, a 2 point stance makes little difference as even with a TE, no one is getting a direct shot at you unlike a NT, DT or 5 gap power end.
But having only seen the write-ups and a few plays, its hard to say.
