Fuck handing off to the back from shotgun, who's standing beside the QB. Marshall's safety was crashing in over and over again and tackling the back before he even reached the line (which was routinely moving backwards). The scheme is more lateral than vertical in general, which makes for some slow, soft football. It only works when you have above average pieces (ala Kyren), with an o-line with a pulse.
Tommy can't adjust on the fly either, so when his scripted plan blows up, he's lost.
ND can and must do better.
