The simple plan is often best.The reads definitely are, as is the blocking scheme. See Urban Meyer's analysis earlier this year. One reason Iowa is doing so well this year is that the receivers and the QB are making the same correct reads nearly every play. Iowa's plays look simple, but there's a ton of detail that goes into every snap. That detail is difficult to master and hard to learn. It's one reason why I wish Iowa would switch to a power o scheme and work more slants and TE/slot waggles under deep hooks/posts/go routes. The reads are simplified, and the passes come out quicker and the underneath stuff is higher percentage. Someone mentioned the R4 offense, and that's what I'm talking about. Iowa is more similar to NE or Manning's Colts. You have to have speedy and smart guys to pull it off.
