Yeah, in the diagrams (especially Figure 3) you can see the patterns on the strong side of the formation always form a triangle (oblique) stretch, which is a staple of Walsh's plays. It's basically a vertical and horizontal stretch in the same area of the field. Also cool is that the QB's progressions are listed (underlined numbers). However, this is very different from what the 49ers run as Walsh's progression read plays differ from Kap's coverage read plays (WRATHman44 and I discussed this a bit in the "Jon Baldwin playing his last game" thread).
As for checkdowns, I think the option to checkdown is there for Kap to use, he just doesn't use them. When watching the pass plays for the 49ers this season, there is always a RB performing a check release, but Kap rarely ever looks to it. He'd rather extend the play while looking downfield, then scramble.
Hypothetical, but if Kap just throws two checkdowns a game, his completion% would go from 58% to 66%. I'm not sure if that logically makes any sense, but what I did was add 32 (2 x 16) completions to his total for this season. I do know that as the play is extended from Kap's scrambling, the LBs start to drop deeper into their zones and the check release is there for about a 4-7 yard gain.
The triangle really is the secret of the whole offense. That is what allowed the Niners to hit at a completion % way above league average.
Speaking of the trinangle the one play in my mind that really illustrates it is the Z-Spot or Spot plays
This play was huge for the Niners especially with Shanahan. Along with Flanker Drive it has always been my favorite quenesstial WCO play.
Spotted this play while watching this game again. Reminded me of your post.
3Q 1st & 10
ARI: Cover1 man
The 49ers put the FB Miller up to the line of scrimmage outside of VD. There was some discussion awhile back about why few teams use a split back formation, even when running actual plays out of Walsh's playbook. Doing what the 49ers did here, instead of split back (pro set) formation, will help Miller get a head start on his route by placing him closer to the edge of the formation, helping him quickly get to the flat.
Below: Boldin goes in motion.
Below: The LB rides VD and tries hard to re-route him. This is in the 3rd quarter after VD had already burned them for 2 TDs.
This is a rhythm throw so as soon Kap hits his back foot on the 5 step drop, a decision must be made. Boldin's and Miller's route will start to break down, versus man coverage, the longer this play goes on since Boldin comes to a stop on the curl, and Miller will eventually run out of bounds. ARI rushes 5 so getting the ball out quickly was a smart decision. Baldwin at the bottom at the screen is running a backside slant, just like in the diagram of the Spot play.
Below: Kap throws it low and away to help Boldin vs PPeterson. It had to be done as PP closed very quickly.
Below: VD finally gets free and looks like he was going for the Corner route, just like in the diagram of the Spot play.
How is Kap's footwork? Threw it off his back leg.
Below: This is why he had to throw it off his back leg. Pressure in his face.
This was run on a 1st down. It netted +7 yards. On 2nd down, it was a Gore run for +1. 3rd down was converted using a short pass by rolling Kap to his right (more WCO stuff!). That was a WCO set of downs, but I don't see this enough to call them a WCO. WCO is a philosophy, not just running some of the OG plays here and there. Really hope to see more of this throughout 14-15 and beyond.
