I think people are asking the wrong question. To me its obvious that Chapman at his best is more valuable as a starter. The real question is whether Chapman as a starter is going to be good, meh or awful. Many don't want to acknowledge that all three outcomes are possible and just assume that he'll be as good three times through the order as he is for three hitters, but that is what the Reds are trying to guage right now. I think the only way to find out is to try it for 3 or 4 months. But if it fails, it could undermine the season. I see why its not an automatic choice, but I'm in favor of trying it. I wouldn't be surprised if he struggles the second time through the order though. I think many here don't acknowledge that possibility.
