Darnold is going to be better. His WRs will be better, his OL will be better, his defense will be better. Running backs? better. TEs? better. Coaches? Better.
The hesitation that he was showing in the QB tape video is central to his problems. Note early in the tape the 2 WRs are engaged in communication at the LOS and then run the same route. Confused WRs kill QB accuracy--they vary speed, alter routes, etc. Play calling? Terrible, from what I hear. The OL? pressure not from one area--from several. Running backs? Nope. Defense? Very Terrible.
I think, when he gets confidence and has 4-5 Stud Wrs, a stud RB, a better line----his confidence will improve and the hesitations will go away. He will anticipate and throw it with authority. He was 23 and human, expected to carry a terrible franchise.
We found a gem. You will see.
