If your definintion of "great stuff" is based entirely on the radar gun, then yeah, his stuff isn't great. Cliff Lee hits, what, 92-93 on the gun? Is his "stuff" not great too? Narveson's got an excellent change and a very good curve that he commands very well (sort of like Lee in that regard too), that he uses to set up his 88-89 fastball. When your location isn't off game after game, it's not happenstance either, it's a skill. If you look inside his 2010 numbers (which I would argue WAS a breakout year), he had a better WHIP as a starter last year than Gallardo.
