Where has the star commenter gone?

After the news of John Motson's retirement from commentary work the question has to be asked where have all the commenters gone? By this I mean those whose work leave a impression on you, for example those whose voice became synonymous with the sport they commented on like Dan Maskell with Tennis and Bill McLaren with Rugby Union. Then there were those who worked on various sports like Barry Davies who in a long career worked many different sports including Football, Gymnastics, Figure Skating and Hockey to name just 4. Of today's crop they are some who were quite famous before they took up the mike like Steve Cram who had a successful career at the highest levels of Athletics, Andrew Castle who is better known for his media career than that of a Tennis player and Garry Herbert whose emotional display at winning gold for the Men's Rowing Coxed Pairs has continued onto his work behind the microphone. You may get the odd exception like Jonathan Pearce best known for his exuberant football commentaries but seems to be sidelined for the big games. Perhaps we just have to wait for the current generation of commenters to imprint themselves on the public in the same way their predecessors did.
