There isn't a position in the NFL draft that carries more weight with teams than quarterback. Every year, the top prospects receive a tremendous amount of attention, both from NFL clubs and the draftnik community.
Unfortunately, the desperate situation that more than a few NFL teams find themselves in has a tendency to give them "tunnel vision" when quarterbacks are concerned. They will look past flaws and ignore red flags in their zeal to upgrade at the league's most important position.
And in 2015, the leading candidate to be drafted high because of the position he plays and not his ability to play it is Baylor Bears quarterback Bryce Petty.
