I'm 13 and i'm trying to go through middle school - high school and hopefully make it to college and play nfl?

i'm 13 and my dream is to become a NFL football player i would like to go to some of the colleges in my city but they teams suck horrible. the colleges in my city is Temple and LaSalle .LaSalle football program got cut they don't do football no more and temple they not on national tv like Texas i want to go to a college where they have a gfreat football team and give me mor chances of being drafted. to the nfl i am a C average student i been a C average student most of my life . my body type is mostly fat no muscle and i try hard to lose weight but i can never seem to lose any so i still gain weight and hope to become a RG,LG,MLB,DE, or Center . i want to play the position that gets drafted the most . i told my mom i wish i had a Big Daddy V body type and i told if i had a Big Daddy V body type i would have more chances of getting drafted by a nfl team for my size. It's wether Football(NFL) or Plumbing.
