Really? He's 59th all time in baseball reference WAR (including pitchers), higher than Joe Dimaggio, Frank Thomas, Reggie Jackson, Tony Gwynn, and Manny Ramirez.
36th all time in OPS+, higher than Mike Schmidt, Willie McCovey, Willie Stargell, Arod, Chipper Jones, Gary Sheffield, Reggie Jackson, Tony Gwynn, Rickey Henderson, Jim Rice, Dave Winfield, and Wade Boggs.
I know he "only" hit 449 home runs, but he also had over 200 stolen bases and a career .297/.408/.540 line. To me, the sum of all that equals a hall of fame career.
