I don't think Fields has an issue recognizing blitzes, I think he overthinks his own athleticism. I think the issue is Fields thinks he can outrun God because he's such an amazing running QB. With time, I think he can correct that assumption.
Processing progressions may be an issue for Fields, but he's much different that Trubisky in how he's doing it. Mitch would lock on to a receiver, JF takes his time reading the D.
Missing "NFL OPEN" wr's? Define "NFL OPEN" for me. I bet 90% of the league misses them.
