Not sure if I made the argument in this thread or another, but your QB needs to fit your offense and talent. They need to be mentally "there." And history is against the successive picks at QB in a draft of having success. Their franchise desperately needs to hit on "the guy." They can't keep putting it off and letting another team make the choice for them.
As fans, we may not see a huge difference between the #1 and #4 QB, but as a GM, you need to make that evaluation. It's why you have a job. There is absolutely no question of what you'd rather have as a franchise: an All-Pro RB, or All-Pro QB. QB every time.
