Rolen is very similar to Ron Santo. Both have 70 bWAR, similar OPS+, were outstanding defenders, and pose dilemma to HOF voters who have a tough time with 3B candidates.
Bill James ranks Santo #9 3B of all-time and Rolen #12—-which seems about right.
Mark Grace had 46 career bWAR—nowhere close to Rolen and Santo—and James ranks Grace #55 among all-time 1B.
If we want to complain about former Cubs getting short shrift among HOF voters, I would point to Stan Hack. Hack had 55 career bWAR, James ranks him #10 all-time 3B (a bit high, probably) but Hack never even reached 5% in HOF balloting and seems forgotten by the Veterans committees. Not quite a HOFer but a better candidate than Grace.
