I don't think we're running more because we have the lead. Before, defenses were mostly dropping 8 and rushing 3 and we were not taking advantage of that by running against a 3 man front. I think we're running more because Will has gotten better at adjusting at the line of scrimmage and also our backs are getting better, so we are taking advantage when people are essentially daring us to run. I don't think Leach has really changed his philosophy. He wants to put pressure on every part of the defense and then take what the defense gives. We just weren't good enough before to run when we should for the yards we should.
Beat me to it. It is this, and a little more. Lately when we run, we're making yards, Yes, the backs are probably getting better, but I'm thinking it may be more about the O-line getting more experience with the wide-sets and how to work with each other in this scheme.
Hasn't it been revealed a few times now that CL doesn't really call for runs or passes. He calls for one of the very few plays he has...all of which have a run or pass option that is up to the QB to decide based on what he reads pre & post-snap. There are typically more pass options, so the odds of there being a pass are greater on any given play.
Also, as Will has shown he can be accurate with his passing and is capable of stretching the field deep, that has also helped open up the running game because it has become much more risky for opposing defenses to keep more of the "drop 7 or 8" relatively close enough to close in quickly on a run or short pass into the flats, middle screens, etc. I really believe Leach is all about calling the formation then relying heavily on his QB to make the right choice and for each player to do his job perfectly. You only get there with repetition until it is 2nd nature. We all know Leach's system has always been about far fewer sets & plays that are practiced to near perfection, combined with an accurate QB who becomes good at making the correct decisions (including changing the play) after Leach has called for one of the few plays.
So, Leach calls a play, we get to the line...the defense shows us a look, and Leach expects our QB to make whatever call he thinks best fits what he is seeing. While most coaches expect at least some of that, I suspect with CL, it's really a huge part of the entire philosophy. He wants his QB to have more freedom than other coaches do, though he expects his QB's to be accurate enough, great at making quick reads & going through progressions.
In short, he likes to get our players prepared to run the few plays we have to as near-to-perfection as possible, then largely allow his QB to decide at the LOS what to do based on the defense. Our defense he leaves to ZA. As our guys have gotten better at learning their positions & responsibilities within his system, we have gotten better across-the-board, allowing for more
successful runs when that is what Will sees as the best option. To my eyes, we tried run plays (including virtual run plays), passes to the flat & middle screens early on, but just weren't blocking them or running them well enough to keep calling them, whether by Leach or Rogers. Our RB's & WR's were getting blown up at, near or behind the LOS too consistently to make it a viable option.
