Well assuming you are asking that question seriously. I'll answer it so.
Among pitchers of his era:
*No. 1 in complete games
*No. 2 in shutouts (one behind Nolan Ryan)
*No. 2 in innings pitched (trailing only Ryan) *No. 5 in Ks
*No. 6 in wins
Okay, only 287 wins, but he played for lousy teams. And Bill James did some research and discovered the following:
He walked through Blyleven's career, start by start, and then compared it to the careers of the best Hall of Fame candidates of that era.
He found Blyleven had the worst run support of any pitcher in the group except Don Sutton and accumulated the most "tough losses," a stat James invented personally to measure losses in which pitchers deserved better.
And then there is this from the Sabermetric Baseball Encyclopedia CD-ROM.

According to that encyclopedia, Blyleven allowed 344 fewer runs in his career than the average pitcher of his day. In the live-ball era, only eight pitchers have done better in that department. And those eight comprise a group that essentially consists of the best modern pitchers who ever threw a baseball: Roger Clemens, Lefty Grove, Greg Maddux, Randy Johnson, Pedro Martinez, Tom Seaver, Carl Hubbell and Bob Gibson.
If you look more closely at that stat, you also find it wasn't just a tribute to longevity. Blyleven had six seasons in which he allowed at least 30 fewer runs than the average pitcher. That's as many seasons like that as Tom Seaver -- and more than Steve Carlton, Sandy Koufax, Juan Marichal or Jim Palmer.
The voters get so caught up with these magic numbers like 300 wins, 500 HRs, 3000 hits, etc.
