NFL scouts consistently tell me that the single most underrated component of the Combine is the "feel" teams get for players through the informal and formal interviews.
Like many coaches (who have worked their up through high school, college to the NFL level), my background lies in education. This has often come up when discussing with scouts how to quickly "size up" players' personality.
No player invited to the Combine lacks the ability to play football. The tough part of scouting is not in differentiating the players who can play, but the ones who will continue the work necessary to improve their play once they are given an NFL paycheck.
In that case, after being less than wowed with some of the higher-rated tackles of this draft that have come through the media room, thus far, I was very impressed with Indiana's Rodger Saffold. The former Indiana player has the uniquely sculpted, yet stout build scouts look for in a left tackle. He was also very thoughtful, articulate and passionate with his answers.
I fully realize how little the ability to impress in workouts means on the football field. Considering that Saffold has already struck me as a woefully underrated prospect due to his size, strength and agility, I (and more importantly, scouts) don't have many reservations about his game.
Soon, they won't have reservations about his intelligence and dedication either.
