It's a conditional question, so here's a wishy-washy answer.
Yes, I'm okay with JH at the helm, as long as we have a really really strong running game next year. We have to be able to pound the rock conistently and ideally, explosively. This year, I'd say we were actually consistent but NOT explosive.
My worry for next year is that with only a "good" or "average" running game, not an outstanding one, we'll be asking too much of JH. And this year, MG was a MASSIVE part of our running attack. His frame and physicality was crucial to the success of our team. I don't see that in JH next year.
Now if JH is to be a significantly better and more accurate/effective passer next year, great. And that changes things.
