It's interesting hearing former NFL talking heads on the radio all essentially express concern in their own way.
This week, I've heard on the radio (usually Mully and Haugh, driving into work), no less than Dave Wannestedt, Sage Rosenfels, and Michael Lombardi all say the same thing (each in their own words) about the Matt Nagy scheme when it comes to play action.
All 3 came right out and said that the Bears don't run play action well because they don't disguise it. Lombardi put it the most succinctly - said that the problem with play action for the Bears, is that to run play action well, you need a single formation that you can either run or play action out of, in order to keep the defense guessing.
However, when the Bears run play action, they do it out of a different formation than their runs, which tips off the defense that a play action pass is coming.
Something so simple, yet Nagy is too stupid to get it. Dude is a straight up fraud.
