The Diamondbacks have one of the most fascinating starting rotations in the league. Not necessarily the best, but definitely interesting. Here are two, plausible predictions you could make about the rotation:
A starting five led by 3 former all-stars and breakout candidate Robbie Ray goes from bottom-5 to top-5 in just one season.
or...
A starting five led by the most overpaid pitcher in baseball and the disappointing Robbie Ray remains in the bottom-5.
A logical argument can be made fairly easily for both sides, which is why I am filled with half excitement, half nervousness.
