Barry Bonds dressed up as Paula Abdul on the first day of Giants spring training probably to create interesting video for his new ESPN reality show. ESPN ombudsman George Solomon says ESPN should put the reality show and its April 4 debut on hold until allegations of steroid use raised in the book “Game of Shadows” are investigated by Commissioner Bud Selig and perhaps an independent investigator. Solomon, a veteran of the Washington Post sports editor, is also troubled by the fact that if any news concerning Bonds breaks in front of the reality show’s cameras, it can’t be used on ESPN’s “SportsCenter” until it airs on the Bonds show first. “Game of Shadows,” of course, is the book written by Chronicle sports reporters Lance Williams and Mark Fainaru-Wada, which cracked the top 10 of both Amazon and Barnes & Noble.com best-seller lists last week, according to the New York Times.
