Purdue is a “concept” team; by this I mean they have a few dozen concepts (give or take) and they build an entire offense off of this. In many ways, this is a very effective way to build a simplified offense that can be executed at a high level; you combine individual concepts and your playbook can grow into the hundreds, but your players only need to learn their few dozen concepts (which includes run concepts). You’ve simplified the game for everyone: OL and QB, and maybe most importantly, for your QBs and WRs. Because what they learn is limited, they can learn it in more detail, meaning they understand the nuances and adjustments that can be made on the fly. The QBs and WRs get more reps running only a handful of plays, and they understand each other’s reads and in-play modifications.
One of the concepts I want to take a closer look at is the Weakside Flood.
