Bill Walton is a jackass, and he has always blatantly favored west coast teams. If your team is matched up against the Lakers, Sonics, Trailblazers, Suns or Kings you’ll get the shaft all night, and its nearly certain he’ll be calling your game. His secondary bias was always towards any team with a “star” center. He always hated the Bulls since their team was built around Jordan and they basically built the template for minimizing the factor of a center. I think it was a threat to his reputation, and his nightmare is a game where point guards rule, which they would if the officials called the game like they should these days. Walton ruined the 90’s for me since he always gave Shaq or Ewing and the Lakers, Blazers, Suns or Sonics a constant blowjob in the finals.
Don’t get me started on Joe Morgan and Jon Miller.
Anyways, I think most broadcasters have a built in bias, and if you’re already a self-concious fan you’ll probably pick it up pretty quick. Considering most are former managers and players, its logical. McCarver is an asshole and clearly is very New York biased. There are certain broadcasters who I think do a better job than most at being impartial. For example, Bob Costas was always the model for it. And I must say for all of Madden’s faults, he does a reasonable job of being unbiased for a ex-coach with his fan-like demeanor. Granted he might get on one topic and ride it into the ground, but I never get the impression its biased, just the most interesting facet of that matchup and he’d be equally likely to do it for either team. He did really over-build Ray Lewis, but frankly for 2+ hours there wasn’t much else worth discussing. I have little doubt that 5 years from now he might do the exact same thing with Courtney Brown without any reservation. On the other hand, I can’t say Theisman and McGuire have the same even-handed tone, they’ll always be biased towards that NFC East.
In short, I’d say in some cases its just paranoia, in others actual prejudice, and occasionally deserved disrespect. Honsetly, how long do you think the Bengals will have to actually be good to deserve consistent hype? Would you honestly rather the announcers made phony praise of every team and player just to keep things level?
