How about Kyle Singler? When he came to Duke he had to bulk up and play the interior, as his career went on he moved outside to accommodate the depth inside. So I guess to answer your question I would do what the coaching staff asked me to do!
But if I was looking to how I would translate as a pro, I would go the wing player, as this gives me the opportunity to play multiple positions.
Either way, shows how much of a team player Singler was in his time at Duke, changed his body to suit the team.
