What are my chances. 10 points for best answer?

Ok what do you think my chances are of making it far with this position. I am not worried about my height (5-3) or weight (120). I am going to increase my weight and height isn't everything in football. Look at Devin Hester, he's only 5-10. I want to play on defemse like outside linebacker and I am dedicated to that position. I am the best tackler on my team and I don't miss tackle to often. I am going into high school next year and I want to stay with that position all throught high school freshman and varsity teams. I am in a small school that went 3-7 last season. So, should I get that position and could i play in coolege and the nfl without a size discrimination.
