No, you may be right. I'm going off horrible memory as well.
I'm not sure Helfrich is the answer as a play-calling OC here, but he sure as hell has a better history preparing QBs at the P5 level with this exact offense than Mario, and will add to the brain-trust. I can't decide whether having Frost, Lubick and Helfrich together again would be a good thing or too many cooks in the kitchen.
I think as long as you have a clear role for everyone and it is clearly defined it can work I guess. I think the big thing is, have someone come in who is very familiar with the scheme (or maybe that's Lubick) and can take over play calling and allow Frost to be a CEO. He clearly is struggling to be a CEO and OC. It's so damn frustrating because we saw him do it at UCF.
