Jay Jaffe uses the JAWS metric -- he invented it, as an average of career WARP and peak (best seven seasons) WARP -- to evaluate the eight players on the 2010 expansion-era HOF ballot. Only Davey Concepcion, Ted Simmons and Tommy John come close.
There likely will never be another player like Rickey Henderson statistically. Baseball Prospectus looks at the current game and finds that no one is really close, but names such as Brian Roberts, B.J. Upton and Johnny Damon fall into the discussion.
