@IrishInOntario "It's not about designing a couple plays. Did you see how Justin Fields looked last year at Georgia?" I could not find this post so I had to piggy back off of another poster.
This is one of the better post on this thread and wanted to make sure that this point was highlighted.
I for one love the concepts that Kelly and Long tried to implement into this offensive game plane, especially the route tree that they were playing off. A lot of the sideline post routes against cover 3 and even cover 2 with the under routes that complement them to make a defense "pick their poison" have been open Book just does not chose the right receiver. For example, We had Claypool lined up at Z and Kmet at the Y. Claypool runs a 10 to 15 yard post toward the middle of the defense while Kmet ran a post toward the sideline. Even if the defense is not in man the read there is going to be a 1,2,3 right out of the break. Normally this 2 route concept forces a defense to either play middle and cover the post leaving the side post open to an over the top in a cover 2 or 3 look or man to man against the OLB which is a good mismatch. If you look at route concepts like this throughout the year Book has not taken advantage of these reads. Book will normally check down to his X reciever who is Finke running a drag route 3 to 5 yards from the LOS which is then normally met with a hit by the MLB or broken up pass, just based on what I have seen. If Finke had more speed to beat the MLB the play could be a little more successful but the fact still remains that he is missing that initial read. Another example is when The Y receiver is lined up with the Z, lets say it is on the right side of the field and lets say it is short side in this scenario. The Y runs a post middle of the field with the Z running a corner route with 3 breaks normally 10 yards at the end of the break (we have seen this exact play before). The read is still a 1,2,3 and is a pick em for the defense which forces a choice by either a nickle back or OLB to chose middle or corner, off that choice that when he has to throw and he does not. You will normally have the H which is the TE run a drag to play side to force the corner to honor the under route which again creates space over the top for the corner route, which at that point the safety decided if he is responsible for the corner route or the post that is coming up the middle of the field. It all happens fast but it is easy to pick up when you watch for it game in and game out. Obviously, it is not a sure fire thing but that is how these route concepts are suppose to work and it you do not read the defense then you are basically just lost back there having to tuck and run or resort to hitting the under route every time.
So, to your point these concepts may be hard to someone like PJ to fully pick up and execute. I will not make assumptions because I never saw practice over the course of his tenure. I do know that when he was in the game the offensive scheme changed. So here is the question, do you taylor your offense to fit one guy, or do you find the right guy for your offense? Chicken and egg debate really, but you get my premise here. I feel like we could have done a better job implementing more RPO stuff into our scheme but again I am not in the room.
