I think I'm too used to German and Dutch commentators, who are generally very well-informed in the sports I hear them in - and Belgian in case of cycling. Same goes for the few English commentators I regularly hear, like Martin Haven (bobsleigh, skeleton, motorsports) and Tim Singer (luge), who really do know what they're talking about instead of just mentioning someones split time and their world ranking.
Then every single time events like this come around, I get disappointed by the level of commentators.
