Bob Costas was back on my show this afternoon. On the heels of his HBO show starting a new season last week with a discussion of steroids in baseball and the whole Barry Bonds controversy, I got into some of those questions with Bob, who was making noise about this issue years ago.

I also talked to Bob about his other network job, wondering why he won’t be doing play-by-play for NBC Sunday Night Football and how NBC can get better ratings with the Olympics, and more.
