If he’s staying in LF, he needs to have “Eloy Rules”... no planting your foot into any walls or fences...no diving near walls...no jumping into stands. He needs his own prevent defense, or he can’t be there anymore. Everything else- the routine stuff, yes he could work on and get better. But bottom line, it’s about the team and putting the best team on the field that eventually wins 90+. If that makes him a DH or 1b at 25, oh well
