summary: 40 times are important for NFL evaluation, but more important when combining a factor for weight. They are using weight * 200/(40 time ^4)
1. No wonder Curtis didn't get much attention as his weight/40 combo formula comes out to 87.5--very low for NFL RB's.
2. I would like to thumb my nose at the entire NFL because I was using a metric of weight/40 time combination in evaluating my youth football team two years ago.
