Is it really the case that 56 percent of NFL players are obese? And why is this taken seriously by the AP?

These folks probably know a bit better. BMI doesn’t scale well. It’s a simple height/weight formula that doesn’t even have the advantage of the arbitrariness of the old charts. I’m willing to admit that the BMI’s assessment of me may be pretty accurate, but that probably has more to do with the fact that I’m in the middle of the pack in height, am not an athlete, and sheer luck than anything else. (Actually, it can’t even be that accurate with me. In order to get to the middle of the normal weight range, I’d have to weigh what I did when I was fifteen and my ribs were sticking out. :) )
