That concept is true for the short term but I think it won't be permanent. Just look at Terrell Pryor's comments as to why he chose OSU over Michigan. It was directly related to becoming a more complete quarterback and being able to be more of a passer than a runner.
One thing about the NFL game that will not change is that a qb's chances of lasting in the league drops significantly the more he runs. The reason that will not change is because players aren't going to start getting smaller and slower. The trend has been and will continue to be players are getting bigger, stronger and faster. Which means they can deliver bigger and more forceful hits at impact which results in more potential damage.
QB's are going to have to continue to do more passing and handing off rather than running if they want a lasting productive career in the NFL. So they're going to be forced (to some degree) to acquire these skills in college to be better prepared. Michael Vick is a great example. He had a tough tough time learning to be a passer in the NFL because he never was required to do that at the college level. A lot of kids will see that and not make the same mistake. Pryor seems to be one of those kids.
i'm pretty sure i said "to a lesser extent" regarding the pros.
it's also more than a short term development. if you look around the league, there are almost 0 of the 80's and 90's style cement footed qbs in the troy aikman mold. even the big qbs like rothlesberger (sp?) are mobile, with the exception being (i'm choking back vomit) peyton manning, who may be the greatest pure passer in the history of the game.
bottom line is that a qb who is a great runner and decent passer is nearly an ultimate weapon in the college game...just look at pat white from west virginia.
and as for kids looking to the nfl, that's certainly true, however, there are also many other run-first qbs who simply want to play qb in college who refuse to change positions...again, see pat white, who is from alabama but was only recruited by sec schools as a db.
after all, kids like white will have a chance to play in the nfl, just not at qb. someone, however, will draft him even if it's in the later rounds to take a shot at him transitioning to wr, db, kick returner, etc.
the option has been a very productive offense since it was first conceived decades ago, and although it's gone through changes over the years, it remains productive and very hard to defend.
it will probably never work in the pros, though, because the defenses are too fast and too disciplined. and we probably lost the best chance to see it tested in the pros when vick tanked himself, because if anyone could run it in the nfl, it would have been he, or maybe steve young, who is probably the greatest dual threat in the nfl i've ever seen.
i agree that vick was always way overrated as an nfl qb...his passing was atrocious at times, but his college career illustrates my point about running qbs in college. he was nearly unstoppable at va. tech. remember the national title game where he juked two fl. state players so badly on one play that both of them blew out their knees?
