Was watching PN (I think yesterday or friday) and one of the commentators was saying "Roglic just doesnt look right today. He's clearly not comfortable on the bike today. Something isn't right" a few minutes before Roglic put in a blistering attack and won the stage
I like the older succesful ex-pro commentators best, people like Phillipa York, and Sean Kelly, because they have been at the pointy end, understand exactly what is going on and can give interesting insights in comparison to their day.
People like Kirby and Ligget are just shrill windbags, whose only function is to act as a counter point.
