okay first we need to clear something up.
People on that football team are most likely in high school, meaning for over half their life, they weren't the ones making the nutritional choices in their life.
One of my bestfriends plays center for our team and he's definitely overweight, but you know something? He works his ass off for hours every day burning off whatever he can, he doesn't like who he is, and he tries to change it, he didn't make himself fat, his mom fed him 6 meals and a day and as a loving 8 year old you're not gonna be like no mom this is going to deteriorate my health later in life!
So don't group them all together, please, that's a really large pet peeve of mine
