Funnily enough, my mind jumped to Martin Brundle as a classic example of a good analyst - or at least he was in the 90s and 2000s. He’s still good, but it just isn’t as new or exciting anymore - he was a fantastic counterpoint to Murray Walker’s boundless enthusiasm with a lot of sensible chatter and in depth knowledge.
Another guy I quite like is Jimmy Bullard, particularly on Sky Sports News or Soccer AM - no bullshit, everything in layman’s terms, and has a laugh with it.
