Well, its like a lot of Reds deals. He isn't any Cy Young winner, but he's probably better at #4 than anyone else we had. He has pitched well from time to time, and really badly from time to time. Whoever observed that we'll never see that second year is right, unless he stinks.
Big concern about him and Graves is that they don't strike people out at near the rate that almost all successful ML pitchers do.
