I agree. Pre-draft workouts have become far too important in weighing the futures of prospects, mostly for every position.
But you have to consider the fact that you need something substantial to separate players with good stats from other players with good stats. Workouts are extremely necessary to provide a line between players who are phenomenal college performers, and players who can perform just as good or better at the next level.
Is this fool proof? Not at all. But scouts have to start from somewhere, and it's alot better than just drawing names out of hats, choosing one guy over another simply because he threw for more touchdowns or won a few more games with his team.
Regardless of your outlook on college football and the draft, it truly is a luck of the draw.
It's as simple as this: Before you know their present day status, do you want Peyton Manning or Ryan Leaf?
Just ask "scout guru" Mel Kiper Jr. He picked Leaf.
