I always enjoy people getting specific. Only problem with that is long posts rarely get challenged. Needless to say, I have issues with some of your takes-
Snap 1: 12:25 Hill pushes the center 3 yards into the backfield
Yeah, that's a generous assessment of what happened. What I saw was a guy who isn't very stout using all his strength to try to shed, losing balance in doing so, and then watching the RB run right past him. Yes, Osa went to the ground too, which didn't help. But saying he pushed the center three yards back when the center was simply trying to get leverage, which he got, seems like an overly optimistic take.
Snap 2: Pass WR screen left. Samuel takes the ball from the 20 to the 4. Osa and Kazee make the tackle.. Hill hustles down the field and almost gets in on the tackle.. As the backside DT..
"Almost gets in on the tackle"? Dude was 8 yards away when the first guy attempted, which caused Hill to slow up a split second. Only reason he was in the vicinity was because of the broken tackles and he still arrived pretty late.
Snap 3: 8:36 1st and 10 at Dallas 47. Hill at the 1 tech. Run wide right away from him by Mitchell for 4.
That play was at 8:48 and Hill is playing the 5 technique on the right defensive side. He also gets away with holding the LG.
Snap 4: 8:04 2nd and 6 at the Dallas 43. Hill back at the 3. Handoff left side for 9. Hill is double teamed but gives no ground. Mitchell cuts left where the rest of the guys have vacated.
Snap is at 8:09. Hill is lined up at the 1 tech. He is not double teamed. He's stopped by the center and Osa goes to the ground from the LG's block, getting on Hill's feet, which causes the LG to just redirect to Hill. Osa is laying between Hill and the LG on the ground.
Snap 5: 7:30 1st and 10 at the Dallas 34. 3-4 look. Hill is the right side DE. Hill penetrates and almost makes the tackles in the backfield. The handoff is to the left but there is a huge cutback lane left because the backers overpursue. Mitchell gets 5.
This one bothers me because it looks like he could've made the play in the backfield. He's playing the 5 again and SF tries to reach block him with the LT, which fails. It looks like he may have let up thinking he would get a holding call that didn't come.
I also would say the LBs didn't, "overpursue." Looks like they didn't get downhill and fill, allowing Mitchell to come to them.
Snap 6: 6:50 2nd and 5 at the Dallas 29. Throwback screen blown up for loss of 11
But what did Hill do? Looks like he got manhandled by the center. He was literally the only guy on the defensive line who ended that play on the wrong side of the line of scrimmage. On a screen pass.
Snap 7: 2:37 of the 1st. 49er ball at their own 22. Stretch play to the right. Hill and Tank on the T/E stunt blow the play up and combine for a 1 yard TFL.
Hill gets his blocker taken out by Lawrence. He better make that tackle.
Snap 8: 2 and 11. Run to 2 hole.. Hill stalemates his man forcing Mitchell to jump cut one gap outside. Unfortunately no backer fills that gap ( I think it was supposed to be LVE) and the result is a 5 yard gain.
What you call a stalemate I say is an inability to shed his blocker. In other words, he gets blocked 1 on 1 and the runner goes right past him.
Snap 9: 3rd and 3. pass slant to Deebo for 19.
But what did Hill do? Nothing? Pretty much.
Snap 10: 10:31 3rd and 3 at Dallas 24. Deebo run to the right side. Hill penetrates and blows up the play. Turns it back in resulting in a short gain. That stop forced the 49ers to kick the FG.
What?!? This assessment makes me think your agenda here is clouding your vision. Donovan Wilson got downhill and blew up that play. Hill ended up on his back, literally pancaked by the guard. Not only that, the guard turned him back upfield to pancake him. You say he, "penetrated," but all he did was attack the outside shoulder, get stopped and redirected upfield on his back. If Wilson isn't playing downhill then Hill's contribution to the play would've meant nothing.
You also missed some snaps-
2nd Qt- :22 left. SF running out the clock. Hill winds up on his back again as they run right at him for a gain of 7.
Next play- SF still running out the clock. A good example of Hill's lack of awareness. His blocker misses the cut block, Hill gets penetration and hits the pulling blocker, oblivious to where the ball is.
Next play- SF still running out the clock. Hill gets sealed to the inside of an outside run. Again, they're going right to his side. First down, half over.
Snap 11: 1st and 10 at the 25. Pass .. Hill flushes Garapolo to his right.. pass incomplete.
Ok. If there was any question as to whether you have an agenda this is the clearest example. You're saying Hill flushed him to the right. There was no flushing. It was a playaction bootleg. Hill's blocker barely touched him because he slanted towards the playfake. He never sniffed Garapolo because dude was bootlegging off the playfake.
Snap 12: 1st and 10 at the Dallas 26 after Dak throws the pick. Deebo on the toss sweep to the right. Hill contains and forced the cutback. Unfortunately nobody is home at the second level and he scores.
I'll agree with that take. Hill kept his position and forced the cutback where no one was home.
Another snap you missed-
11:49- it's a pass. Hill stunts to the outside looking to contain. Nothing happens, he's not even blocked.
Snap 13: 10:34 1st and 15 at the 39. Deebo run to the right. Hill stalemates his man forces cutback again. This time his teammates show up.. gain of 3.
When you say, "stalemates his man," I think it's your optimistic way of saying he got blocked. He's playing the 1 technique and sheds the center 5 yards downfield. But you call that a, "stalemate." Further, he doesn't cause any cutback because he's not on the playside and the RB goes straight to the hole without redirecting.
Snap 14: 2nd and 11 at the 43. Pass.. Hill penetrates, flushes Garapolo.. Jimmy G throws a lollipop on the run that gets picked off by Brown.
Again, this is one of those, "what are you watching?" moments. Osa penetrates and forces Garapolo out of the pocket. Hill stunted to the outside as contain. His inability to contain allowed Garapolo to get outside. Luckily, Garapolo throws a pick. Hill had almost nothing to do with it.
Snap 15: 5:37 1st and 10 at the 39. Inside run for 2 yards. Osa and Hill stalemate the offensive line
Not a stalemate, got blocked again. Allowed the blocker to get leverage on the inside for the runner to cut off his hip. LVE fills the hole.
Snap 16: 4:29 1st and 10 at the 42. Inside run left. Hill at the 1 tech now, submarines and blows up the play for no gain. Mitchell trips over him and the lineman.
Poor feet, no balance, gets yanked down by the guard and gets in the way. Another one of those, "rose colored glasses," takes.
Snap 17: 3:45 2nd and 10 at the 42. Outside handoff to the right.. Hill was still at the 1 tech. Short gain..
That was a 3 tech he was playing. But yeah, they ran away and he was a non-factor. Barely even blocked.
