Even Giambi was a guy who had high SLG's in the minors prior to using. I feel Giambi would never be the same player without the drugs, but he would still have some power in the bigs. Sosa barely scraped .400 in SLG in the minors. He was a 6' 160 something pound kid who seemed to balloon to 220 rather quickly. He of all people was someone who went from being a no power OFer to a power star quickly.
I dunno. Giambi's admission while nobody else admitted is a big step for me. Then his half assed apology was still an apology. It is guys like McGwire, Sosa and Palmeiro that make me sick, because we know what they did, they just keep refusing to acknowledge it.
