My litmus test on offensive play calling: On 2nd and under 4, if you call anything other than i-formation power running for the next two plays in a row, you're not as smart as you think you are.
Langsdorf fails this test far too often....
He needs to simplify, stop trying to outsmart the opposing DC and just bring it. Too many OC's appear to feel the need to get tricky but sometimes they to recognize they just need a hammer.
