Is that OBJ at the top outside? Is he looking at DPJ running the Slant from bottom up?
Doesn't matter. Not taking the 1st down with Felton was pure idiocy and inexcusable. Priority 1 is keeping the drive going so that you get to stay on the field.
I'm pretty sure you can see Baker look at Felton first and then turn his head a hair before the defender flips his hips and takes off. At that point, Baker is scanning downfield, so IMO... ok fine. But as he's running to his right, how does he not see Felton STILL uncovered just past the sticks? I get that it's sometimes hard to find any/all uncovered receivers, especially after you've already come off that read... but Baker has already run to the right and cut his field in half, and there's a bright white jersey standing all alone right where the ball needs to go.
