That's my point. So he won 18 games and threw a no-no. What was his record last year? 9-6? With a 4.85 ERA? And how about 2003? 14-12 with a 4.01 (okay, that's not all that bad...). Those are average stats AT BEST!
Not to mention that the no-hitter means he was great that one day. Remember David's Cone perfect game? After that, he couldn't get a guy out. Not that Millwood's the same, but a no-hitter doesn't mean a pitcher will continue to dominate afterwards...
