Easy there, Samu. The comment you quoted was meant as a joke. You know, Cofidis rarely wins, so who would know a rider? Just a lame joke is all.If you make a living as a commentator and you can't do that, I think you should find a different job to be honest, cause then you haven't taken your current one serious enough.
Unless a commentator was assigned to a grand tour and given weeks to learn about every single rider in the peloton, I can't see why anyone should be expected to know everything about every rider. If that was a job requirement and the applicant didn't fit the bill, they wouldn't be hired.
Also, I can't see why anyone would get angry about something like this, but that's just me. Seriously, who the hell cares?
p.s. At least the comment wasn't directed toward the lovely and talented Carlton Kirby.
