Literally the only difference is they've been using Luepke as a FB a decent amount whereas the past couple years they had an OL moonlighting as a FB on some plays here and there.
The run designs look almost exactly the same and most of the run formations are exactly the same.
No, s0n. In prior years it was primarily zone scheme, NO actual FB on the roster. They'd use offensive linemen or a TE as a fullback. We now for the first time since Parcells, have an actual dedicated FB on the roster.
"We're not changing anything in the running game" other than losing Zeke and adding a FB for the first time in decades.
