No al, it's just that not everybody has the same encycolpedic knowledge of baseball as you do. I never knew the dude pitched for the Royals.
I did, and I think "well" might be a stretch. If you're comparing him to the rest of the Royals, yes; otherwise, I think he was just slightly above average.
Slightly above average is well, particularly when you do it for 210 innings a season.
He was durable, I'll give him that. He was usually at the top of the lists for hits, walks and home runs allowed, though, and had an ERA of 4.79 and a WHIP of 1.42 during his time there. Even the Pirates wouldn't sign him for more than $500K as a free agent.
I'll agree that he's a fair bit better than his second stint in Boston would indicate.
