Quick correction-- Rick Gentile (and the Nagano Olympics) were part of CBS' coverage, not ABC.
In that particular case, what I think he was saying was that the CBS crew had invested more time in Michelle (as the gold medal favorite) than Tara-- via fluff pieces, research, etc.-- so the natural inclination was for the CBS crew to root the one they felt they "knew" better. But at the end of the day, the producer's job is to tell the story that unfolded-- whatever it happens to be. I think Gentile feels they he did that successfully. And the director's job is to present each skater's program in the best light, regardless of who it is (I should add that Bob Fishman, who directed in '98, made no mention of having a favorite. To be honest, he directs SO many different sporting things in a year I don't think he has time to pick favorites!)
As for Meg Streeter-- while she clearly formed opinions of certain skaters as she went along, I think she by and large she kept those opinions to herself (at least at the time). The one she was more concerned with was Dick Button-- remember that she once talked to him about toning down his comments so as not to hurt the skaters' feelings... even though she later felt that she'd made a mistake!
You make a really good point about the whole idea of broadcasters getting so invested in the skaters! With so many of them admittedly in love with this sport, I guess it's fair to call it a job hazard at times
