On the 4th and 1, I disagree with the analysis. This was a counter play and was run exactly how it was called. Problem was, you don't run counters against an 8 man front on 4th and 1.
The entire line is blocking to the right (See 52 B.Jones and 62 J.Williams and how they are facing in the picture and compare Leslie's position to where he was lined up in the 1st picture). This was a designed play for the line to block right and Car to take a step to the right and then run off Leslie.
Problem is, you only have 6 guys blocking 8, and with the 2 unblocked guys crashing right (along with 62 Williams missing his block), they are in perfect position to stop Car.
This was a terrible play-call on 4th and 1 and is completely on the OC.
The other play was completely on King. 1) He has Dunbar wide open in the flat as 17 reads King's eyes. If King hits Dunbar, possibility he runs it in for a TD. Still, Bonner had space in the endzone, but King underthrew the ball. In that type of play, you throw it to the back pylon and let Bonner be the only one that can make the play. His underthrow allowed 17 to enter the picture and make the pick.
This one was the right play call, but poor execution by the young QB.
