I agree with your last statement 100% which shows this staff has absolutely failed at requruting and developing a QB out of high school in the last 4 yrs. I have seen Desormeaux in the past play his butt of injured, can't say I see the same level of toughness at that position today.
I don't watch practice, but no doubt about it in the small sample we have of games, Davis can extend plays with his feet better than we are seeing now. Many times I've seen receivers covered AJ have all day then he chunks it out of bounds. JD could turn that into positive yards with his feet. Also no question if he is running zone read it would open things up for Eli as they would have to respect his ability to run.
Not saying I have the answer but ULM hung 40 on that txst D and we not going to see another defense that bad. If we stick to status quo it will be a long 2nd half with very few points.
