I think it's obvious that the major culprits of the steroid era (McGwire, Palmeiro, Sosa, Conseco, Bonds, et. al) are either long gone or greatly diminished now, and we're certainly not seeing any 1-year wonders any more that were clearly roided up (Brady Anderson, Bret Boone...Luis Gonzalez?). Of course the "power outage" is due to the crackdown on PEDs.
