I think Ryan is almost universally mis-valued. Either people think he's a top-5 all time elite talent or they think he was barely above average, depending on which stats they choose to look at. Obviously that makes me, the lunatic in the middle ground, right. I would say the following pitchers have been better than Ryan (in no particular order but the order in which I think of them, which is somewhat chronological and somewhat order of talent, but I don't think I'll miss anyone):
Walter Johnson, Christy Mathewson, Mordecai Brown, Pete Alexander, Lefty Grove, Bob Feller, Warren Spahn, Tom Seaver, Jim Palmer, Greg Maddux, Sandy Koufax, Randy Johnson, Bob Feller, Bob Gibson
That would put Ryan at 15th, which is pretty darn good. Then, just so nobody accuses me of missing any of these guys, here is the group that would immediately follow Ryan:
Ed Walsh, Eddie Cicotte, Cy Young, Don Sutton, Pedro Martinez, Mariano Rivera, Dennis Eckersley, Steve Carlton, Addie Joss, Old Hoss Radbourn
Any questions?
