Well, those emotions and passion are a very good trait of a commentator, no doubt... but it was also Murray's weakness, forcing him to make too many mistakes. I have watched a fair amount of old races with Walker commentating and too often he gets overexcited ("Is it ? Is it ? Oh my god, this would be an incredible turnaround!! This will blow the race wide open!!") without concentrating, what really happened, and co-commentator correcting him moments later as a result. Passion and emotions are very good, but it would be better if they were controlled and canalized in the correct way. In fact, while watching any sports, it's a bit annoying, when commentator gets something completely wrong, while every casual TV viewer can comprehend immediately, what really happened.
