it depends on what your good at and where the team needs you best
qb
a guard?
if you are in junior high, most positions, if you are full grown, good luck at any positon, but if you did play, i would have to say punter\kicker
it depends on what positon u play but halfbacks need stong thighs and calves to drive through tackles
Catcher!
defender
Wide receiver.
First Base.
Power forward
attacking midfield or supporting striker
Shooting Guard (SG)
The best move in the positon.
