I don't think it's that simple. You don't have to let every player "fail" at the best position they might be able to play.
Machado going straight to 3B was a fantastic decision by the s*** birds, for example. He was an uber-elite 3B and likely more valuable there than he would have been at shortstop.
Bo's internal clock might be a bit too tightly wound for short. Less thinky more grabby throwy might suit him better.
