How can I improve my skills at Running back ?

I saw your clip and you look like you would be pretty good in high school. But in high school, you go up against bigger people than in that video I saw. But you look really good. Your only flaws are your height (in high school, you would get crushed if you are 5'5) and your weight (150? Eat your meat and potatoes, kid!). Otherwise, you're ready for football!
