Harrier's statement deals with team perceptions. He's not saying that you can't pick up a QB in later rounds who will turn out to be a "Franchise QB".
Here's the statement in question:
He's absolutely correct. No team thought that Geno was a "Franchise QB", which is why he went in the 2nd round. He also states that it's possible that Geno could end up becoming a franchise QB.Franchise Qb don't fall out of the top five, if teams think that Qb can be a franchise QB. Not one single team thought Geno Smith was a franchise QB. Now Could he develop into one. Without a doubt.
