Evaluating football players is an inherently subjective undertaking, and never more so than when Tim Tebow is the one under the microscope. To some people, he's a champion in the making; to others, he's an albatross.
But NFL general managers and scouts don't have the luxury of subjectivity. They have to set a value on every player in the league and every player who might enter it. And while they guard those valuations as trade secrets, there's one time a year they can't avoid sharing them, down to the percentage point: during the draft.
