"I think everybody got caught up in the steroid situation and forgot" about Biggio and Piazza, Rose said.
Rose treads more lightly around first-time nominees Bonds, Clemens and Sosa, warmly praising all three while still reserving full endorsement of their Hall worthiness.
"The only person I'm going to defend (from) yesterday ... I've got to give Roger Clemens some slack," Rose said.
"Here's a guy that says to this day that he didn't take steroids. He's never flunked a drug test, and he went to two courts and they both ruled in his favor. So I don't know. And I know there's suspicion, but you don't not vote for a guy because of suspicion."
Rose agreed to a permanent ban from baseball in 1989 after the former Cincinnati Reds player and manager was accused of betting on baseball. He is also banned from inclusion on the Hall of Fame ballot, although four voters gave him write-in votes this week.
Rose said he recently reached out to Commissioner Bud Selig for more dialogue about his possible return to the game, but has no progress to report. Rose thinks Selig is probably tired of hearing his name, which he would understand.
"For me and for all of his fans, it's unjust," Kim said. "We want to see him in the Hall of Fame more than he does. He doesn't want people feeling sorry for him. He knows what he's done."
Rose claims he doesn't think much about his own ineligibility for the Hall during his everyday life with Kim, a onetime Playboy model, and her two children. Their reality show, premiering Monday on TLC, is a survey of their unusual life titled "Pete Rose: Hits and Mrs."
The episode featuring their trip to Cooperstown clearly affected Rose and Kim, who don't live together full-time. While Kim and her two children live in the Los Angeles area in her own home, Rose's primary residence is in Las Vegas, where he eats Subway salads every night of the year and watches sports every night of the year, including three baseball games a day during the season - but not waiting for the phone to ring.
"You have to understand, I'm not in that Parade (of Legends) because it's my fault," Rose said. "It's not Bart Giamatti's fault. It's not Bud Selig's fault. I'm the one that (messed) up. Why am I going to get mad at anybody else? All you can do is keep your nose clean, be a good citizen, and maybe someday you'll get a second chance. But when you (mess) up, you can't blame other people. You just hope they understand you committed yourself, and that's one thing this (reality) show will do. It will show a different perspective of me."
