Here are 5 non-go routes
where it appears to me he is reading the defender and getting open.
I think you may be reading too much into defenders outclassed by a WR AND QB AND their teammates who all seem to execute well.
Clip 1 is a set play. Guyton takes a false step to the outside then loops back inside under the other WR who immediately scraps off Guyton's defender when he tries to run parallel with Guyton to the inside. Meanwhile the entire right side of the OLine played Toreador with the left side of the DLINE, releasing immediately and running downfield as blockers. The center shoots out and gets just enough of the sole LB to make the play work. The OLine wasn't reading Guyton's false step, they were committed to this play prior to the snap. Going long down the sideline wasn't an option, IF Guyton did that there would be 3 linemen illegally downfield.
Clip 2 is also a set play. There's a safety playing center field who back pedals on the snap OUT OF SIGHT. The outside WR runs a short curl. Guyton shifts his weight to the inside (field) foot getting the CB to turn his hips, on the hip turn Guyton cuts away for the center fielder to the outside where the ball is already headed. Smoth move by Guyton but the play was going outside.
Clip 3 also strikes me as a set play. Guyton runs at his CB who drops straight back, when he does Guyton cuts inside and runs parallel to the goal line. The S or OLB makes the play when SKIPS 3 times (watch his feet) backwards and to his left arriving very late thus taking himself out of the play. Had that defender just backpedaled on a straight line he would have been in the passing lane and the QB would have looked at another receiver.
Clip 4 also strikes me as a set play. The WR next to him runs a curl keeping a defender short while Guyton's man backpedals and takes away the sideline. He gives Guyton the inside and (Guyton takes it as he has no where else to go) but the CB gets no Safety help until the play is over. The QB ran PA while the two receivers on his left crossed their patterns. The Slot goes long while the outside WR crosses underneath to the inside. The Safety bites on the Slot going long leaving Guyton the middle of the field. It strikes me as a well diagrammed play where the QB has either one on one coverage on the Slot going long or Guyton depending on where the Safety commits. BTW, after the PA the QB looks one way, then the other, selling the play.
Clip 5 strikes me a set OUT. On the snap the CB IMMEDIATLY turns 180 degrees and runs downfield with his BACK to Guyton. Guyton's take 5 steps and cuts outside catching the ball 15 yds downfield. Once again in single coverage with no other defender remotely close. The other WRs run varying routes downfield then all cut inside. It appears two of them were open as well. Guyton was open if he hadn't run the out route as the CB committed the 180 turn on the snap. The QB could have hit him for more yards had Guyton continued on a straight line. At least until Guyton ran up up the CB's back.
I like Guyton but don't see Quinn and Shark or Rees and Floyd reading the defenders and changing the route, in or out, short or long, accordingly.
I see a TEAM executing, smart offensive plays, well.
