I didn't like Huw Johns when I was a kid - always seemed old and stuffy - but as I have become old and stuffy I think he was really good. Better than Wolstenholme, but he had the famous phrase that encapsulated commentary (and blighted it in some ways as many others seek that famous line - back to "balmy night in Barcelona").
Motson, I disliked intensely, especially in that 2002 World Cup "Breakfast with Beckham".
