I've watched that play over a dozen times and most everyone did OK. Except for Joe Jackson.
At first, I thought that the LBs were out of position, but they were in gap control. Smith COMMITTED to his gap by taking on the blocker that came off of Hill. LVE covered his gap, but stayed free to run to the ball.
The FS was providing deep coverage, so I didn't really expect him to charge in hard. If he does charge in with any consistency, the flea-flicker becomes a thing.
Both DTs were doubled and pushed around, but each occupied TWO OL and each clogged up one gap.
The last OL was on Hyder, so the ONLY DL that was NOT blocked by an OL was Jackson.
But Jackson was completely taken out of his gap and ridden out of the play by a TE. Fortunately, Sean Lee cleaned up Jackson's mess there.
It does look like Hill ended up on the ground, but this single clip isn't really clear about that. One of his draft weaknesses was that he is on the ground a lot.
Not enough here to say that Hill is a bust. He's definitely raw though.
Mainly, I'm disappointed in Jackson. The Draft Network said THIS about him: "Run Defense - Sets a firm edge, plays with extension and maintains outside leverage. Could stand to be more deliberate about squeezing down the b-gap. Dominates tight ends attempting to turn him out."
That simply did NOT happen.
WalterFootball said THIS and it seems to be more true, at least on this play:
"Jackson needs work in the ground game. He flashes the ability to hold his ground and stand up blocks, but there are too many plays on which he gets pushed out of his gap or knocked around. In run defense, Jackson is better when he works upfield and uses his speed to cause disruption in the backfield. He needs to get stronger in his lower body to hold his ground at the point of attack. With more development, Jackson has the potential to be a balanced defender who is a solid contributor against the run."
