Have you ever coached football??
WRs...
and played. Its not that hard.
Playbooks are all variations. There are standard sets you remember and variant off of them. Its not that freaking hard folks
When fridge was here we had like 60 formations. But literally 15 plays (exaggerating a bit...). The variations are alignments...lining up as paul would call it.
Zone blocking for running play is the same whether 21, 11, 10 etc. Its all the same assignments. Center gets MLB after doubles the 3tech until next level etc etc etc. It really not that complicated. A lb blitzes A gap C comes off double gets that zone otherwise next level.
there are only so many routes you can run. The x lines up on the numbers, etc. All formations, plays and alignments are based off the numbers and hashes. All DL are based off head up or offset. All OL are based off of DL fronts and gaps. Its ALL THE SAME scheme to scheme. The variants and style you employ change coach to coach. Only so many routes in a route tree.
CB plays inside tech...no matter the D, 2 deep, man, etc, if he plays inside tech the S help isn't going to be there, you try to cross his face in a slant option. It doesn't matter where you are in the world of football...this is the same. If you are a cb lining up inside the number playing inside tech, you better not let that wr cross your face and gain inside leverage (we suck at this under roof)
The assignments, plays etc are all REALLY similar.
This is like anything. If I said to you tell me how to play Cuse's 2-3 zone. You would be like, ok I know what a 2-3 zone is...but then I said tell me their philosophy on baseline defense in the 2-3. you may not know. Sure of course you may not know their trapping philosophy. But its really easy...it would take a total of 10 minutes for the base concept and then you learn the variants.
Guys, we do 4th order physics problems. Not sure what everyone acts like football is hard.
