The offense and Tebow have come under fire a lot recently and for good reason, it's just not working. To help myself understand why it's not working I had to watch some of my daughter's Alma Mater's games this season and it was very revealing.
For some background, my daughter attends Ga Tech who is coached by Paul Johnson, formerly of the Naval Academy, who runs a wing "T" triple option read offense. Their offense is built around the run. They run, run, run, and when defenses crowd the box to stop the run, they try to hit the deep ball. If the corners play too far off, they sometimes throw a WR bubble screen and hope the WR can break a tackle and then it's off to the races. Our very own Demaryius Thomas grew up in this scheme.
The Broncos offense has been built on these same principles. We mix in a combination of 12 personnel (1 TE, 2 backs), 21 personnel (2TE, 1 RB), pistol/shotgun spread, and we also put in some jumbo fronts with an extra offensive lineman. We run the ball and force the defense to adapt which is supposed to, in theory, open up the passing game by providing single coverage on the outside with typically only a single high Safety.
Here's the rub... Our running game is working as designed. We're piling up yardage and lead the league. The problem is, our passing game is ineffective. Why? Is it Tebow? Is it the WRs? Is it the play design? It's all of the above.
First off, the passing game is extremely elementary when it comes to route design. Often, there are only 2 or 3 receivers in the pattern. Often times, these WRs run deep routes 15+ yards downfield, often they are "go" routes, occasionally with a double move thrown in, or are deep comeback routes. These are long-developing routes which rely on the threat of the running game and play action to hold the LB's and Safeties and allow the WRs to beat single coverage.
Unfortunately, our WRs struggle to beat single coverage - especially when CBs know the route ahead of time - and because the box is already loaded to stop the run, it's very easy for those run stoppers to become pass rushers. Now, you're dealing with an overload blitz scenario and if the CBs can hold their coverage for a short time, the QB has no time to deliver the ball and if he must scramble the WRs are too deep to reliably make an on-target throw down field. The WRs must break off their routes and come back to the ball, which happens sometimes, but because they are so deep it takes even more time to get back to the QB. When the WRs do come open early, Tebow is hesitant to throw and the window closes. He also tends to look deep instead of taking the underneath stuff (if it's there) too often. This allows the defense to close on him while he's waiting for the deep routes to uncover.
So what is the fix? The way I see it, a loaded box should be a QB's dream but we must shorten up the routes. It will help the WRs get open and help vs the pass rush. With the scheme we're running, we've got to use more quick slants and short crosses. This will require Tebow to be accurate, but he can hit a 5 yard slant - he's done it before. It will also require him to make quick and smart decisions because with a loaded box, he'll have to worry about hands getting up to bat down/tip passes. It's no surprise that most of the "elite" pocket passers work the short game to their advantage and use it to beat the blitz (Manning, Brady).
Bootlegs and rollouts with the option to run should be incorporated more, also. Forcing the defense to commit to Tebow's running opens up routes underneath and helps the offensive line avoid holding calls as they try to maintain their blocks while Tim runs around. If it's a designed bootleg/rollout, the O-line knows which way to block and is on the same page, it's not just another scramble drill.
Will this work? I don't know, but it seems as if we aren't even trying. Our playcalling is very predictable and has been easily defensed of late. Tim needs to learn to check down and pull the trigger on open receivers, the receivers need to learn to get open and catch the ball, and the OC needs to help his offense by calling plays that don't take 5 seconds to develop all the time.
Hopefully, these things will come to fruition in the offseason. These plays are probably already in the playbook, we just don't use them. Our passing game struggles because none of the three phases are on the same page. The playcalling, the QB execution, and the route running are all sub par. Fixing the playcalling and making it a little simpler for the WRs and QB is the first step.
