So, yeah, they have a lot of dynamic weapons and can score fast, but it all starts with a Najee Harris or a Jacob Lacey and a big nasty offensive line running right over your ass. Same thing with Ohio State. It's what they do.
I think Estime and the OLine/TE group can certainly be that (Estime reminds me a ton of Harris when I watch his tape and look at his measurables). So yes, add the other stuff on the perimeter...we need that. But lose the physicality and the "run their asses over" aspect of the game and we will be absolute garbage. If we go back to not being able to run the ball against a Georgia or a Clemson or an Alabama and we will be just as inept as we were before.
Truth is, if Alabama or OSU all of a sudden couldn't run over teams and couldn't run the ball against teams and just had to throw it, they'd be garbage too.
