Respectfully disagree (Im sure you've heard that before coming from me

). While you make a good a point, he has
demonstrated his ability to win. Last year would have been drastically different had that chain not slipped. Also twice finishing second to the one widely considered the world's best stage racer in the sport's most prestigious race makes for an excellent case. Besides, if not Andy, who is the second best?
To answer the original question? It's hard to say, I don't see much of the media overrating riders, but I do see fans and compatriots. As for a rider I think is universally overrated, I just can't say. Cycling is so specialized in it's focus. Maybe Andre Greipel is an overrated sprinter. Until I see him beat Cav or consistently finish within a length of him, he's not anywhere near the second best sprinter as many consider, but he has shown breakaway power which can potentially make him a good classics rider (small group sprint at Roubaix perhaps), so is he actually overrated? Know what I mean?
