When I first started posting on more intelligent baseball boards a few years ago, I came across a couple ideas I hadn't much thought before. The first was that Curt Schilling, Mike Mussina and Kevin Brown were all fairly similar to eachother, and the second was that they all probably belonged in the Hall of Fame.
Sean Smith's WAR would seem to agree with the first point very much, as this graph shows. The second point is up for debate, but, on this graph, I've included a Hall of Famer that few disagree with for comparison: Willie McCovey.
Over the last couple decades we've been blessed with four of the very greatest pitchers who have ever lived, and they were all at their best in a very close period of time. As a result, I think the Mussinas and Browns got forgotten a little as second rate pitchers, but they were still very much great. Over recent years, it's become accept that Tom Glavine and John Smoltz are Hall of Famers (with good reason), and it seems Mussina may have joined that class as well (with more difficulty than he should have faced). Schilling might be in that group, too, but Brown -- always seemingly underrated -- belongs in their conversation, as well.
Also of interest, perhaps in a later piece, is a third tier of pitchers behind even this including names like David Cone and -- to my shock -- Bret Saberhagen who aren't so far behind this group that they should be easily dismissed (though I know Sabes already has been).
