Week 6 Buff Bills Coaches Film Analysis Thread

Here's the very next play after the busted coverage I showed. No bust in coverage or technique, we just get out-played.


Right after the last play, Buffalo comes with another smash concept. This time, we're in man-coverage.


At the start, Reid is in good position. He's maintaining outside leverage with inside help.


Though, he's not fast enough to keep up with the WR who gets vertical and stacks him - he's now lost his outside leverage.


With the WR having stacked on Reid, he's clear to run to the corner of the endzone.


Taylor does do a good job of leading his receiver out and has good ball placement for a 30 yard TD.

Looking forward to seeing how McCoy gashes us all game. From what I saw, the defense just sucks on every level.

Yeah, I was goin to dedicate tomorrow to that....lucky me...

There's gotta be a whole confluence of suck to get to 300+ yards in the NFL. Kinda gotta touch the guy before he gets 5-6 yards downfield. Also, I loved how the wildcat and unbalanced lines mesmerized us.

Yeah, pretty much.... it was LOL bad sometimes.

But, that's for tomorrow, I'm busy the rest of the evening so I won't be able to post anything more until tomorrow.

Hey Jonnydel. Can you tell me the review video about Eric Reid was good to read for tackle? I bet. Reid was aweful to read and avoid to tackle.

We've seen defenses attack the 49ers run game many ways over the past few weeks. Giving false reads to the QB to trick him into thinking there is a numbers advantage to run the ball. Scrape exchage where the DE and LB switch gaps. The Nut stunt that puts stress on the center.


Here, BUF runs a stunt on the weakside to confuse the blocking assignments. What BUF does here is risky, but it will pay off for them. This is on the 49ers first drive of the game. Very manageable down/distance.
The 1tech (red) switches A gaps (nut stunt)
The 3t (orange) attacks his gap.
The OLB (yellow), lined up over the C gap, sells out and attacks the weakside A gap. This leaves his C gap (Staley's outside shoulder) completely undefended.


Hyde is about to get the handoff and sees daylight. What he probably doesn't see is the OLB (yellow) looping in.


Notice Hyde making a cut to run to the weakside A gap. But there's no more daylight. Beadles sees The yellow OLB and abandons his block, which blows up the entire play.


Punt.

I'll show a way to counter the scrape exchange, but wanted to refresh minds on what it was.
1Q 2nd & 19
Red is the key defender on this zone read.


Red crashes down to get the QB to keep the ball. Yellow LB scrapes over the top (exchange gaps).


-3 yards.

I don't get it. Why are we double-teaming? Teams are beating our run game with 6 in the box.

This should not be happening at any level.

"If we feel [the defenders begin to tighten their techniques] or we start to get twists and blitzes on the inside, we run the outside zone play,"
- Chip Kelly at a coaches clinic

Outside zone left. Red and yellow will switch gaps.


Red crashes down. Yellow scrapes over. Because yellow was at normal LB depth (4-5 yards), Staley is able to move upfield, get good leverage and good blocking angle.


Hyde gets the edge.


+4 yards

Yeah that's a good question. Many times I see Staley stay with the double team too long, completely finishing the DE off. He'd be better served to apply a quick double team, then move up to a LB.

Both our Tackles and Guards double teamed a DL each.

was Beatles supposed pull right there? would've helped...lol.

This is the first, "wtf are we doing out there" moment and it came on BUF's first drive of the game. BUF has a 2nd and 21 after an offensive facemask penalty. 49ers are in their nickel package.

Power left. Backside guard (red) pulls to lead.
This pic is a few moments before the snap. Gaps are labeled so that we can try to assign which players have which gap(s).
Strongside A = ?
Strongside B = DeFo
Strongside C = Bellore
Strongside D = Lynch
Let's just say Wilhoite has the strongside A. Huge bubble gap, but fine.


Right before the snap, DeFo and Lynch shift inwards and the pic below is right at the snap (center's just snapped the ball). So now Lynch is over the C gap.


I think DeFo is two gapping because he gets out of his stance and engages the LG while not trying to penetrate. Okay, so DeFo is two gapping (A and B gaps).
Lynch should have the C gap, but Lynch knifes into the LT's inside shoulder, which is the B gap. Bellore loops around and takes the D gap. Who has the C gap?


That's not a running lane, that's a running interstate highway


+16 yards. BUF would eventually convert their 3rd & 5. Then fumble the ball to the 49ers. Still, can't allow a Power play net 16 yards to get the offense into a manageable 3rd down distance.

This is hilarious. Look how far downfield the guard is before he finds work. what the hell is O'Neil doing....

Agreed, I too thought there was an open passing option on that play and thought, "well, can't complain, 29 yard gain".

Agree on the lateness of some of those throws. It's always been one of my complaints against him and I was looking for him to be more on-time in this game. It might be rust and not being used to the live-game speed. However, it's also something he's struggled with since 2012.

One such play that sticks in my mind was a swing to Davis in the left flat. It appeared obvious from the snap that was the play. Davis slipped out easily and was open all the way. CK looked at him and waited until he was near the sideline before gunning it to him. The location forced Davis to do a 180 and was unable to hold the ball on a difficult catch. Had that ball come out earlier Davis would have had time to put a move on an otherwise late arriving defender and pick up 5-8 yds.
