I'll be back with the Davenport Translations from Baseball Prospectus, and perhaps a word from Bill James, but got a kids' thing to tend to.
The DTs attempt to recalibrate stats throughout baseball history into a park-neutral, era-neutral and league-neutral context. Actually, era-neutral is really translating stats to a modern context. We're all familiar with the park-context of Coors Field, for example, or with the pitching dominance of the late 60s. We had the dead-ball era, and the 1930s when everybody and their dog hit over 300. Let's put all that into the pot and see what DT has to say...Thus translated, Biggio posts a career batting line of 289 / 374 / 459, compared to his raw stats of 283 / 367 / 436.
Some comps mentioned in this thread:
Biggio 289 / 374 / 459
Sandberg 282 / 346 / 488
Whitaker 286 / 377 / 474 (very underrated)
Alomar 309 / 382 / 474
Yount 297 / 358 / 484
Comment: Biggio doesn't stand out here, although he's right in the mix. I think all of these guys are HOF material.
BP has other interesting counting stats. Let's look at 2 of them. Their premier all-encompassing WARP3 and Runs Above Replacement (which consider both batting and fielding prowess, compared to a replacement level player at that position).
Player / WARP3 / RAR
Biggio / 123.5 / 1098
Sandberg / 112.9 / 1020
Whitaker / 123.9 / 1098
Alomar / 131.7 / 1182
Yount / 136.8 / 1231
