Helton has about 4000 ABs at Coors, and a similar number on the road. That's not a small sample size. And the results are pretty clear: Split G GS PA AB R H 2B 3B HR RBI SB CS BB SO BA OBP SLG OPS TB GDP HBP SH SF IBB ROE BAbip tOPS+ Home 1132 1075 4801 4000 867 1381 315 28 225 850 24 15 709 505 .345 .442 .607 1.048 2427 96 29 2 59 99 46 .347 119 Away 1103 1049 4600 3913 527 1124 271 9 142 547 13 14 624 657 .287 .386 .470 .856 1839 89 28 1 33 86 38 .312 80 Like some others (Walker, Dante Bichette and Vinny Castilla coming immediately to mind), Helton was a very good player made great (more than 20% better) when playing his home games in the best hitting park of his era... not just the best, but a historically disproportionate and perception-warping park. He had a 200 pt higher OPS at home, mostly based on the slugging numbers. Was it his "fault" for playing at Coors? uh, no. But neither should he be rewarded for playing there, particularly these days when we can accurately measure park effects. So would you put a .290 BA /20 HR/.850 PS 1bman in the HOF? [on edit] It's not a crazy notion, but if you want to lower the bar that much at that position, he goes in after Jeff Bagwell (obviously, not to mention the PED guys, McGwire and Palmiero), as well as Keith Hernandez, Don Mattingly, Steve Garvey, Fred McGriff, John Olerud, Cecil Cooper, and Will Clark, and maybe just before Al Oliver, Boog Powell, Dick Allen, Norm Cash and Gil Hodges. And that's just off the top of my head. And if you did the same thing with the backlog of players at other positions, as well as lower the bar for future players, the HOF becomes a museum with hundreds of plaques of very good players, and its imprimatur becomes virtually meaningless.
