i mostly disagree on this [lots of edits since i found the Cards video]
the video above switches to all-22 at :40 secs in the video -- AND has a running play clock embedded
lets Zapruder film this:
1. I think Darrel Williams (top right) needed to run his route deeper-- more to the top of the "A" to give room to go over the top of the Raider short zone defender. This, with 2 below is Kylers first read as he looks right at the snap (about 2.5 secs into the play).
2. Hollywood (short right side) isnt open. Decent chance that ball gets broken up, or, he is tackled without getting into the endzone
3. Kyler then looks to AJ Green in the back as he scans to the left.
4. Ertz is open -- he clears around 2.8 secs into the play. At 3.2 secs Kyler looks like he is pumping to go to Ertz. At 3.4 secs, Ertz is covered. Also, the Raider d-lineman you see comes free into his vision and Kyler pulls it down.
this play kinds sums up the variety of struggles. Decent play design, but (IMO) Williams doesnt quite run the route properly. Ertz does come open and Kyler needed to be .2 of a sec faster getting to (what looks like) his third read.
