It's easy to notice a grooved fastball when it gets crushed. Lots of pitchers groove pitches and get away with it, seemed like Drew never did, though. I remember when twistedlogic posted a GIF of Aaron Sanchez hanging a curve ball to Ortiz that he didn't swing at, and some people acted like the pitch was thrown by God himself.
We need to try to remove bias from our viewing experience. I think Hutch has a great arm and is fully capable of being an average or perhaps above average starter.
