Never played football in high school or anything but...
Quarterback - Love being the leader, in control, strategizing, scrambling, and chucking the ball to the receivers
Defensiveback - The feeling of knocking down a pass or making an interception and taking it the other way are the most satisfying plays to make in the game I think
Receiver - Hauling in a long pass for a touchdown, another great satisfying feeling
MLB- love being a leader, and love hitting people. Crossing routes were always my favorite. Always was a great feeling when a team tried that and you were there waiting for it, and well, good night.
