I'm hoping we don't see that weak rollout QB option this game. If KM was someone who could break a tackle, or was even willing to get contact it might have some merit. Unfortunately the D knows so long as there is a defender within 5 yards of KM he's going to pitch the ball to the RB so they aren't going peel off the RB. Chalk that up to one of the "cute" plays that works great for some CFB teams and has no business in the NFL unless you have a QB with enough size to run thru traffic.
KM is going to gain yardage with his legs when the scramble presents itself, not with designed runs.
