Strong safety or MLB or Fullback?

well, im 5'8, 160 lbs, and i have a 5.0 forty yard. i bench 225, squat 335, and my vert is 25. well, the reason im asking this is because im having people tell me to play one or the other!? i appear to be good at blocking, due to the fact in gym i can block a kid whos 260 pounds, believe it or not. but when we hit sleds in gym, i can pretty much lift it easily, so im just asking for opinions. and YES i will ask my coaches when the season starts....
