John Mayberry: Bust or Steal?

I think Mayberry can be a good player with his power and run production, Mayberry is also built like a powerful corner outfielder who bats sixth.  His only weakness es are his defense needs some improvement and he needs to get on base.  He looks like a good player but I don’t think he will ever reach his full potential, Istill think he will be a useful part of a team, if he does his best he will be a average starter with tons of power, if not he will be a useful pinch hitter.  The Phillies will have a good power teamfor the next couple years with him on it.  I think Mayberry will be more of a bust than a steal but he will a decent pinch hitter, who succseeds twice every ten times with a homer.
