My bad I misunderstood the what you were saying. I thought you were having trouble running the ball in general.

Like it's been suggested above maybe your oline no longer meet key threshold stats. Or maybe the opponent(s) you faced with your new line are better at stopping the run than opponents you faced before. Those seem like the simplest solutions to me. Could just be a fluke as well. Hope you get whatever it is figured out

Thanks bro. Appreciate it!
