I am of the personal opinion that we should not select a QB at 4 (and I honestly don't think we will). What I could see happening is Jerry trading back into the end of the 1st round to select his future QB, that way he has the 5th year option.
Seriously! All of us are undertaking the job of armchair GMs here. It's what we do. I know I am not alone in thinking we should draft someone other than a QB at 4.
