What american football postion should i play?

your not big enough to play any kind of lineman position for a high school and most likely not even a linebacker
for offense i would suggest either WR or if you worked on your arm maybe just maybe QB
for defense i would suggest safety or CB but youd have to increase your speed

First, you should learn to proofread. After that, it's up to you. 40 times really mean nothing. For starters, unless it's done professionally (ie by scouts, etc), you're not getting an accurate time. Furthermore, it is your onfield speed that determines whether or not you're fast enough for a position. Making good reads and adjusting to offenses before the snap can give you a better jump on the ball, so it can allow a slower person to play a position fit for a faster player. Anyway, you said you're not that fit.... it's impossible to really tell what that means, but if you're saying you're not that fit, I'm assuming that your 40 time wasn't done properly, and that ya have some extra padding that you could cut out. Work on that. You're still young, so you could also probably bulk up some and play linebacker, or if you would lose a little weight and increase your speed, you could play safety. If you'd prefer offense (or play both ways), I'd look into runningback. You seem to have a decent frame for it, and because you're young, you could even bulk up some, and move to fullback as you get older. In college, I was about your size and weight (but very, very fit), and I played safety for a D-1 school. When I was 17, I was probably 30 lbs lighter, and I played safety for my high school. The best thing you could do is tell the coach you would play anywhere and do your absolute best when trying out. If you are a good fit to play football, and put in a good effort, he'll find a place for you somewhere.

Touchdown.

offense-TE
Defense-D line

end guard tackle..........................sit at the end of the bench guard the water bucket and tackle any one that comes near it lol lol lol lol lol lol lmao

Tight end for offense and for defense linebacker

playmakers, and game changers play WR.

Defense- LB
Offense- WR

wide reciever and cornerback. if you're good at hitting maybe a safety instead.

TE FOR OFFENCE AND RE FOR DEFENCE OR U COULD BE A FAST DT
