Re: Chapman to start? Maybe not
Arroyo's statement is completely fair. And I don't think Reds brass disagree with his assessment. But you don't know if you don't try. Chapman certainly won't develop reliable 2nd and 3rd offerings pitching out of the pen. That he's so physically gifted is precisely why he should be given the chance to develop those skills.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
