Career value
Some find peak value too narrow in its focus to be a preferred metric for evaluating MLB Hall of Fame performance. They tend to emphasize career value, which rewards sustained performance above peak excellence.
In the Hall at present, there are numerous examples of candidates justifying both approaches. Sandy Koufax is the prototype of a peak candidate. He stood out for only the final half of his 12-season career. But between 1961 and 1966, he ranked among the best pitchers in baseball history, averaging a 160 ERA+ (that’s the pitching equivalent of OPS+) and a 7.75 WAR.
Koufax’s teammate, Don Sutton, is a good example of a career candidate. Sutton’s five-season peak ERA+, 658 between 1971 and 1975, is solid but not remarkable in comparison with some of the candidates on this year’s ballot. Nor is his 22.6 WAR for that period.
But Sutton performed well for the bulk of a 23-season career, eventually compiling a 68.3 WAR. That would rank ahead of any of the nine current-year nominees.
From the perspective of a judge favoring career performance, who are the top candidates? Here’s how the nine rank in career OPS+ or – in the case of John — ERA+.
Player Season OPS+
1 Don Mattingly 1982-1995 127
2 Dwight Evans 1972-1991 127
3 Dale Murphy 1976-1993 121
4 Dave Parker 1973-1991 121
5 Ted Simmons 1968-88 118
6 Lou Whitaker 1977-95 117
6 Steve Garvey 1969-87 117
8 Thurman Munson 1969-79 116
9 Tommy John 1963-89 111
And here is the rank when the standard is career WAR.
Player Season WAR
1 Lou Whitaker 1977-95 75.1
2 Dwight Evans 1972-91 67.1
3 Tommy John 1963-89 62.1
4 Ted Simmons 1968-88 50.3
5 Thurman Munson 1969-1979 46.1
6 Dale Murphy 1976-93 45.5
7 Don Mattingly 1982-95 42.4
8 Dave Parker 1973-91 40.1
9 Steve Garvey 1969-87 38.1
Those preferring a career standard are likely to instinctively marshal around Evans. After that, the standard becomes murkier. That’s especially true in the cases of Whitaker and John, whose careers look far better if the standard of measurement is career WAR as opposed to career OPS+ or ERA+.
