Don't understand how some of you guys come up with this.
Some of the commentators on the list, are excellent at noticing the little things in races, that make all the difference, like when someone is making ready for an attack, when a team is changing tactics during a stage, the battle for position leading into an important part of the course, etc. - They can usually also identify riders fast, even from overheads, by stature and riding style alone.
The rest usually have to wait for radio tour to tell them what is going on - or for TV production to do it for them - and then commentate of the obvious stuff, like telling us what the signs production puts up is telling us.
That you guys rank for instance Frost high is laughable..... I mean, nice guy and everything, but as a commentator he sucks.
For instance yesterday, when Chris Anker was alone in front, you see Mads Petersen (captain of the danish team at this race), break rank and move up besides his 3 team mates pulling the peloton.... he gives an order..... and the tempo is increased drastically, and in that moment, the break is doomed.
Meanwhile, while we all watch this going on, Frost says nothing, he just watches it, then keeps talking about Chris Anker being great at maintaining the gap to the peloton, and that he may have a chance.
To rank him second is simply not on
Rolf Soerensen is head and shoulds above everyone else as a commentator, he sees things before anyone else.
Nygaard, Anker and Ritter are pretty good too.... the rest, not so much
