OK Mr. 6'2 257 there are a few possibilities here. If you really are 6'2 257 and you still aren't on varsity then you are either really fat and slow, or you are a big puss and you're scared of getting hit. if neither of those are correct then you must just strait up suck. haha
You are a piece of work! Follow me closely and all joking aside, take the advice I am about to give you.
This "Mr. 6'2, 257" played football and baseball before you were born and has a son that plays JV football as a free safety. After high school, I played college baseball. Due to the profession I am now in, the military, I am still in excellent shape and run about 20 miles a week...I don't sprint as fast as I did when I was your age, but still can move very nicely, thank you, can easily bench your bodyweight several times, and would be just overjoyed to be able to smash heads again. My playing days are over...I thought you would have caught that with the "child abuse" reference I made.
My advice for you and others playing in high school now...Get your tail off these message boards if you really do play and are serious about concentrating on your game. As adults and "has-beens", we can talk smack and have a good time at it at a mature level. Don't clog your mind with messages from people from around the state that you don't even know...and most are not football players, but fans and parents. Someone should have told you this before.
I support ALL of you young athletes and wish you the best...quit lowering your standards as a young man by arguing with an unknown person and saying they suck, are fat, etc., it doesn't get you anywhere.
Now turn this computer off and go read a book!
