Great job with all the work. You may have just sold me on getting the coaches film next season. Keep it coming. I would love to see this every week, but I understand that this takes alot of time to go threw and you did a great job breaking down each play. Once again awesome job man!

Great analysis. Those Hunter and Reid breakdowns were great, and the Wilson touchdown makes a lot more sense now. Reid biting on the PA is something you'd never know happened without seeing this all-22, and I assumed Willis misread the play and screwed up like I think most of us did. Didn't realize it was Reid's mistake.

I loved this, AJ and I will be talking about Gore again this week and I've already done a review of some of Gore's big plays against the Seahawks. If you could take a look at these two plays:

1st and 10 at SEA 34(Shotgun) F.Gore up the middle to SEA 30 for 4 yards (E.Thomas, K.Wright).
--> end of the 1st quarter
1st and 10 at SF 26F.Gore right guard to SF 34 for 8 yards (R.Sherman, E.Thomas).
--> early in the 2nd quarter

I'd be interested to see if you see what I see RE: Gore's vision (and cutbacks)

Here's the 2nd run you asked about. Here, it's not as much about Gore's vision, Roman called a great play and the O-line executed really well. Then Frank finishes with great power on the run.



Roman calls a "wham" play here. He tried it earlier in the game but, as I'll show later, I think Kaep misreads the alignment. On a "wham" play, which we heard a lot about against Detroit, the guard, Boone, leaves the 3 technique(outside shade of the guard) unblocked going down on the 1 technique. Goodwin moves the 2nd level to the linebacker. TE Vance McDonald takes on the 3 technique with T Anthony Davis taking the DE and Vernon Davis going to the 2nd level trying to find anyone to block. Gore is set to run outside the TE and inside the T or a "2" hole run(0 hole is right size of center, 2 right side of guard, 4 right side of tackle, etc)



Here you see the development of the play



the Wham block gives McDonald an excellent angle on the 3 technique and Goodwin does a great job of sealing off the linebacker. As Greg Roman says, "geometry never has a bad day." Frank explodes through the gaping hole and cuts back following Davis



You can see the wall the O-line and guys create for Frank, he cuts back and gains another 3 yards after contact. It may not seem spectacular to get an 8 yard run, but, if you can get your running back 5 yards downfield before anyone can make contact that's a great play for an offense.

very cool, detailed analysis. if you don't mind me asking, where do you get coaches film from?

+1. Keep them coming. Very happy to have a thread dedicated to this.

Hoovtrain, the coaches film is available to anyone with $60 (might be cheaper now that it's week 15). I feel it is a must in order to understand what is going on in the secondary, which is where everything is unfolding on pass plays.

I can do this now cause I'm taking care of my sick father with an absence from work and have a lot of spare time on my hands. Plus, game rewind is on a 7 day free trial

So you are saying this is just one big tease?!

Guilty as charged. The reason I thought it was on Willis was from how he turned and hustled towards Willson. I was not sure if Willis had bit too hard on the play fake, then realized his man just ran past him, or if he ran hard because he realized "holy s**t no one is in that part of the field!".

That play actually shows how good willis is. He knew right away Reid was out of play and gave chase.

Totally in agrrement that SEA does not do anything exotic with their coverage schemes. Like you stated, very straight up cover1 or cover3. Rely on the ferocious pass rush, then grab/tug/claw and hope the refs get tired of throwing the flag.

I'd like to get your thoughts on the 49ers coverage schemes. They seem very exotic to me. I see them playing pattern match type coverage. My hypothesis is that they (Fangio) have their CBs play so off (large cushion) in order to read and diagnose the patterns that are developing in front of them, then react accordingly. This takes super smart DBs. I often see a zone look that morphs into man coverage as the routes develop. This is very opposite of 'straight up'. Not to derail this thread from the SEA game. Perhaps we can touch on this later.

I'll give some examples later, but, I can only speak to the Seattle game as I haven't had time to go through all of them yet. For the Seattle game, we played mostly zone. The reason why is because of Russel Wilson. When guys are in man coverage they have to turn their back to the QB. When you watch Seattle play, when they get base man coverage(meaning no blitz) Wilson will take off almost half the time. So, when we played man we implored Bowman as a spy(following the QB). With Zone, you have everyone facing the QB, but, you HAVE to get to the qb within 3-4 seconds. We didn't do a lot of exotic things either. But, we did disguise more than the Seahawks did. The reason our CB's were off so often was for disguise purposes. We gave a quarters look most of the game. From there we went to, mostly, cover 3, or cover 2 and sometimes cover 4. Fangio liked to use Reid in this game moving downhill towards the line of scrimage. So, he would often line up deeper in a 2 deep safety look with off corners and then at the snap fly down into flat/run support coverage with Whitner rotating over the middle of the field and the corners playing deep 3rd.

they play best imo when they play man to man on downs that can go either way.
and zone on obvious passing downs 3rd and long or medium type situations

Zone though, allows for better alignment against the run. When you're playing man-man, you're going to give up a strong side alignment every time, unless you give up outside leverage to a TE making the short outs open all day(this is what Dallas gets a lot because Romo doesn't run too much and they run between the tackles a lot, hence why the short out to Witten seems to always be open). Against a zone run team you will have a RB cutting back on you all day.

me too. shows how little we actually see as fans.

do you have the run where Franks hits the pile then flies out the other side for a gain of 15 or so when everybody thought he was stuffed?

With this play, there wasn't much on the coaches film that you didn't see on the broadcast. Pretty much Frank hit the hole he was supposed to and somehow squirted through
I'm working on showing how we got some good passing plays soon

look at you bein all useful and stuff
jonnydel, maybe you have already answered this, but how would you compare Kaep to other QB's who are known to go through their progressions? Specifically how often do those guys go through theirs and what % would you say Keap is going through his per game? It seems he is getting better with his progressions, but there are still plays being left on the field.

This, it drives me NUTS to see our CB's so far off and backpedaling on 3rd and shorts (as an example). I like your theory t.
Great thread Jonny! It's what I was just wanting to add to the thl/NC conversation. Thanks for you work!
