That's cos he really understood the sport...and was a fan too.
Similarly, Martin Brundle in F1
Yeah Brundle's good and the stuff Billy Monger is really good given his young age, a wise head on young shoulders

I was going to mention Murray Walker and F1 and can remember back in the 80's an awful lot of people pulling their hair out and saying he should be got rid of but i'm glad they didn't.
He was a true enthusiast and lived for and loves the sport, I can forgive his Gaff's and looking back it's now funny how the other commentator who lets say had their finger on the pulse a bit more would correct him but in a really nice way as if it was your old grandad

Murray Walker's best quotes
"There's nothing wrong with the car except it's on fire"
"With half the race gone there is half the race to go"
"I imagine the conditions in those cars are totally unimaginable"
"Either that car is stationary or it's on the move"
"Do my eyes deceive me or is Senna's car sounding a bit rough?"
"And the first five places are filled with five different cars"
"And this is the third-placed car about to lap the second-placed car"
"The battle is well and truly on if it wasn't on before, and it certainly was"
"Two laps to go, then the action will begin. Unless this is the action, which it is"
"I'm going for first" (Explaining away a British Touring car driver putting up his middle finger)
Murray: "There's a firey glow coming from the back of the Ferrari!" - James Hunt: "No Murray, that's his rear safety light"
"Let's watch this typical Formula Ford start!" (instead they promptly all ran into each other)
"It's a sad ending, albeit a happy one, here at Montreal for today's Grand Prix"
"Andrea de Cesaris, the man who has won more grand prix than anyone else without actually winning one"
"Unless I'm very much mistaken... I am very much mistaken!"
"And now excuse me while I interrupt myself!"
"The young Ralf Schumacher has been upstaged by teenager Jenson Button, who is 20"
"It would have been Senna's third win in a row if he'd won the two before"
"I'm ready to stop my start watch"
