This is the first 4th down play of the game. It was 7-0 and the defense had been playing well. On one hand you can say that's why Kyle went for it, the defense was playing well. On the other hand, the defense playing well is a reason to punt and put CAR inside their own 10.
This looks like a modified version of Kyle's Follow concept where a drag route (yellow) clears out the middle for the angle route (red) to follow behind it. The red route usually comes from the backfield instead of the slot.
vs Cover 1 Robber
When Taylor (81) starts his drag, the CB on Taylor will pass Taylor off to Kuechly, then replace Kuechly as robber. Kuechly (59) is looking to wall off any shallow crossing routes (Taylor).
Taylor sees it and steps towards the LoS in order to avoid contact with Kuechly.
Kuechly reaching for air.
Hoyer looks to Taylor then moves to Kittles (85), but the robber (CB) takes Kittle's route away. The pressure gets home and Hoyer is sacked.
Because Taylor was aware to avoid making contact with Kuechly, he is able to create separation. But Hoyer has moved on with his progression. Perhaps next time, stay with Taylor because he's a mismatch against a LB in the middle of the field, even against one of the best in the league.
Hoyer looks to Taylor then looks to Kittles. Trust the little guy to win against a LB.
