I personally think the idea of having the right coach and system is as important as having the QB.
We have seen a ton of QB's go number 1 overall, these are guys who appear to have elite skills and talent to succeed at the next level, but it turns outs less often then one would like to see. The biggest reason, the number 1 overall QB goes to a horrible team with poor coaching and a lot of times is there to 1. save a coach and GM, 2. Work with a new unproven coach who his hitching his career to this young player. That is a ton of pressure and leads many to fizzle out without ever reaching their potential.
While Andrew Luck did turn a team that was 2-14 into an 11-5 team, the year before they went 2-14, they were 10 and 6 so even that situation wasn't dire.
There is a reason, that in a draft that saw 5 QBs go round 1, the one that went later in the draft is having the most success. Last year Jackson wasn't asked to carry the team, just do enough. Wilson, in a very good QB class, has been by far the most successful QB, a big reason was landing on a team that he did not have to carry until recently. They had a top level defense, and elite run game early in his career. Brady, Rothlisburger were brought along slowly, hell even Brees had to change situations in order to get his career going.
So I'm not willing to just throw all the picks at QB and hope that magically fixes everything, because in the past it has not; Jeff George, Ryan Leaf, Vick, RGIII...I think the time it did work out was for Eli Manning, but in general, when you give a ton of assets you take away players that could help the QB be even better.
So if we end up at 5th, 6th or whatever, I think the best option is to stand pat, keep those assets to improve the rest of the team and grab the QB you feel best fits what you want to do. If that is Fromm, then draft Fromm.
