For their part, prosecutors sought an order from U.S. District Court Judge Susan Illston preventing Bonds' legal team from showing transcripts of grand jury appearances and interviews with investigators of former San Francisco 49ers Jerry Rice and Terrell Owens and San Francisco Giants General Manager Brian Sabean as well as others. Prosecutors don't divulge details of those statements, but argue they are irrelevant to the trial.

I never heard anything about sterioids and Rice or TO....I'm not a legal or steriod guy so can anyone tell me what the paragraph above means please?
