I agree with you almost completely.
We have all read/heard what a charming, down-to-earth, nice guy the "real" Rush is when he is not ensconced in the "Attila the Hun" chair. Well, this sports show (the kind he's been whining to get on for the last couple of years) would have been the perfect place to display that. Instead, he chose to appear as the same old stiff-necked, pontificator. The format of shows like this is non-confrontational kidding and typical "my-team's-better-than-yours" boasting. I can think of another show on ESPN where his opinion might have been appropriate but not this one.
Rush has his own show and huge audience on which he can and does espouse his peeves, but in his zealousness he just can't lighten up in public. It's sort of pitiful if you think about it. I really believe the guy loves sports, especially football. But, he just couldnt leave his work at the office. I have the feeling that, if you could slice his head open, nothing would fall out but politicians and plutocrats.
