Re: MLB 2014: I paid the $20 mil posting fee for the right to start this thread
My point remains that, just like Bonds and Clemens "were Hall of Famers" before they juiced, Rose was also a Hall of Famer before the gambling. They cheated the game just as Rose did. Rewarding them while still punishing Rose is wrong.
This is comparing apples to oranges. The "cheating" of the PED users (placed in air quotes because the rules were unclear, because there was little if no enforcement, and because the now-sanctimonious sports media was celebrating the achievements of PED users at the time) to improve their own performance (in a manner conceptually no different from players who used spitballs or greenies) is categorically different from endangering the competitive integrity of the sport through involvement in gambling. And the thing is, even if he was exclusively betting on his team to win, if they get cold and he loses a bunch of money, all of a sudden he's in trouble and subject to influence by bookies who might appreciate it if he swung and missed a lot in a few particular games.
As for Bagwell, I think he clearly juiced (although, he attributes his massive weight gain and subsequent increased home run capabilities (guy hit 6 HRs in all of minor leagues (850+ PAs), like 50 in his first three full seasons, then all of a sudden nearly hits 40 in the strike shortened 1994 season) to "working out"). I think he probably deserves to be in the Hall at some point in time, but I'm going to put in guys like Bonds, McGwire, and Sosa before I put in Bagwell.
As for Piazza, I honestly don't think he juiced, and I also think he deserves to be in. If not for a backlog on the ballot, he would definitely have been on my top 10.
That's an interesting point about Bagwell's growth of power. On the other hand, he was already hitting for some power and steadily growing in the early years of his career, 15 as a 23-year-old in 1991, 18 as a 24-year-old in 1992, 20 as a 25-year-old in 1993. Obviously 39 the next year is a quantum leap, but not (to me) as suspicious a leap as, say, Brady Anderson hitting 50 that one year in his early 30s when he'd demonstrated nothing like that during his developing years. I also wonder how relevant it is (this is just speculation on my part, so take it for what it's worth) to Bagwell's HR power that, between 1993 and 1994, the fences at the Astrodome were both brought in and lowered in the corners. It didn't produce a similar power explosion in other Astros hitters, so it's probably besides the point, but it might be relevant. In either case, I think he's a better candidate (just by virtue of having been a better player, irrespective of PED issues) than McGwire or Sosa, but clearly all of them are far back of Bonds.
Piazza hit for monster power in the minors and, even before that, was described by the only amateur scout ever to file a report on him thusly: "Large arms and forearms. Big hands. Broad shoulders. Solid long legs. Very young. Still possible growth left." And this was when he was a 6'3" 195 lb. 17-year-old. The same scout said he had above average power potential. He was a lightly-scouted late-round draft pick because, at that point in his career, he was a right-handed-hitting first baseman described in the same scouting report as a poor fielder.
Amazin' Avenue did a great post debunking the "power from nowhere" myth about Piazza during the last HoF voting cycle. You can certainly knock his candidacy by pointing out that, after being a poor-fielding first baseman as a kid, he turned out to be a catcher with a poor throwing arm whose value was largely due to his bat, but I don't think there's much reason to believe that he was a PED user. (I'm biased, of course.) I think he will eventually go in; "best hitting catcher of all time" is the kind of distinguisher, like "good as a starter and a reliever" for Smoltz as I mentioned last week, that voters love. (Whether that's really true or not is perhaps open to debate, and I think Yogi Berra and Johnny Bench might have bones to pick with the assertion, but there certainly are people who believe it to be the case.)
