Piazza already opened the barn door to get Bagwell in, and now we have to pick and choose among the rest.
Bagwell and Piazza two were guys "everybody knew" were juicing but somehow managed to stay out of the fray.
Per WAR, Piazza, Sosa, Sheffield, Abreu, Edmonds and McGwire are in a range (around 60) where there induction would not be controversial in a vacuum, but that is also the territory of the "critical darling" players like the Evanses, Lou Whitaker, Sal Bando, and Buddy Bell.
And that is a tier below guys like Manny and Beltran, whose career spanned the 'roid era into the sign-stealing witch hunts and probably won't ever get in. And might not have even w/o the scandals at the end -- he just played for too many teams, and the Hall likes things simple and stupid in that regard.
But good lord. I've been an Astros fan for 43 years now and in that half-season we had him back in 2004, he was the best position player the Astros have ever had. In my experience. I didn't get to see prime Cedeno, back when it was looking like he was Willie Mays II, Dominican Boogaloo, but good god Beltran that year -- clutch easy-swing bombs; stole 28 bags w/o getting caught / and man, watching him patrol center was to see a great and gifted artist at work. I don't think any center fielder in baseball history was playing better than Beltran was that year. He didn't sustain it as long as the true greats, but he was just sheer perfection out there.
Regular season stats don't really show that -- esp the old-school ones -- but everybody who was paying attention remembers the playoffs that year. When he'd step in the box you were as certain of a huge hit as you were VY pulling out a third and 12 against Okie State. Failure was not conceivable.
