I think that's exactly the reason why Robbie Earle in particular is so good on the US feed I occasionally stream. I can only think of him as a Dons player but he is analytical and objective gives real insight, that you'll never get from the legion of ex redshirt idiots here.
I've said before when listening to the City app Andy Morrison and Michael Brown are excellent in this regard, certainly don't have blue tinted glasses on, makes their commentary much more interesting.
There was a mad thread on here a week or two before about 1970s celebrities on a sports show. Apparently the City one was Kenny Cockney Lynch! But I'm sure I read football commentator Brian Moore was on the show, his club was spurs. In those days most commentators were Londoncentric definitely had a "big club" bias but weren't sneering towards the less successful. I genuinely think Barry Davies who was apparently another spurs man, was my favourite commentator. He was no Robyn cowen!
