Reggie Jackson thinks all of Alex Rodriguez's numbers are tainted because of his admission to performance-enhancing drug use. Jackson also doesn't believe players who used steroids should be allowed into the Hall of Fame. "Al's a very good friend," Jackson said of the Yankees third baseman in the latest issue of SI. "But I think there are real questions about his numbers. As much as I like him, what he admitted about his usage does cloud some of his records."
