Quarterback is by far the most important position on any football team and there are a number of qualities every coach wants their quarterback to have.
Of course arm strength, accuracy, intelligence and decision-making skills are important, but so are the intangibles like leadership and charisma. A quarterback's personality is a big deal and the NFL Combine is the perfect place to showcase personality due to all the interviews players have to take part in.
Having covered the Scouting Combine for several years, I've watched personality help boost the stock of quarterbacks Jake Locker, Christian Ponder, Tim Tebow and Mark Sanchez, among others. Sanchez may have been the most charismatic... until Griffin.
Griffin's comfort in the spotlight and magnetic personality likely made believers out of some of those in the room who may have doubted him. If as successful in team interviews as he was in front of the media, he'll may be able to do the same with them, as well.
RG3's magnetic personality won't get him drafted at the No. 1 overall spot but coaches and scouts need to know that the quarterback they draft is somebody that their team wants to follow. If he can show that he has the physical skills as well as the charisma, his draft stock could rise higher than it already has, which is actually kind of impossible at this point.
