I by no means am a Jaylon supporter, in fact I want him benched as soon as possible, but he didn't do anything wrong on this play.
The defensive line is in a slant to the left, funneling it to the LB overstack on the left. At the snap all of the defensive linemen go to the left. The ones that blow it on this play are A. Woods(99), Crawford (98), A. Smith (58?)- cant see number, and X. Woods (25). Griffen (97) has the back side contain.
A. Woods is the one that screws up the most. Instead of slanting to the left he for some reason turns and starts to follow the center that is pulling. If he stays on his slant he meets the ball carrier at 15 yard line. Instead, they didn't even have to block Woods as he takes himself out of the play. Crawford is next in line as he gets completely washed out on the play, he ends up practically on the sideline. Next is what I am pretty sure is Aldon Smith on the end. He isn't doing anything but standing there. He has the contain on the left side and if they would have bounced it outside, Smith wasn't going to do anything because he couldn't get off the block of the TE Hooper, who isn't on the team to block. Finally, there is Xavier who does what he is suppose to do but just can't tackle.
The reason Jaylon isn't wrong here is because like Griffen he is responsible for backside contain. Jaylon reads the pulling center, the one Woods decides to chase for some reason. Jaylon knows that only Griffen has the backside, so it is Jaylon's responsibility to fill any backside holes. He sees the center pull and does what he is suppose to do, flow away from the stack on the left.
In actuality, this should have been a 15-yard(?) penalty on the Browns for an illegal block. The left guard engages Hill (72) with a block and the right tackle Willis (71) immediately dives at Hills knees, now he misses with only a glancing blow but technically that is illegal.
