Also, tap into the individual stats listing at your favorite website, and sort by IP, by SO, by SO/9, by ERA - there is no evident pattern that putting up lots of strikeouts harms the ability to go many innings. This is empirical evidence that goes along with what Brock said: some of these guys are just plain *good*. (And there are guys like Dickey and Guthrie who succeed without the Ks. It takes all kinds.)
