Right. Williams is in a different galaxy from Bear. Marcel Reed was a much better dual threat guy (at least when we faced him) last season. Maiva, too.
Different QBs for sure, but all those guys could win with their legs. Bear is a decent QB, and can hurt you with his arm, but he needs his legs to complement that.
I think ND is going to implement a plan similar to how they treated Colton Joseph week 1, and do everything they can to take away Bear's legs and make him beat them with his arm. We'll see if he can.
