You really are dumb. Not one of these three is truly overhyped.
Ferrer: Not overrated at all, because no one here expects him to win slams or even reach a slam final. People have realistic expectations of him, which you have a problem with because you so obviously UNDERrate him. This is the deal: you think Ferrer is too LIKED on this forum - but that is hardly the same thing.
Goffin: Same thing here. I haven't seen anyone hyping him, I've only heard said that he's one of the more talented youngsters - which is true. If your problem with him is that he has not yet achieved anything then the same goes for Tomic, Dimitrov etc. (Both of which are more "hyped", I would say.)
Rosol: Wrong yet again. The only reason he is mentioned as often as he is, is not because people expect great things from him but because mentioning his name is a very effective strategy for provoking sensitive Nadaltards who have basically sworn to hate him forever for that one Wimbledon match.
Tomic has reached QF at Wimbledon beating Soderling on the way, R4 in Australia beating some good players on the way. And he is a talented player; although he does kind of lack weapons, he does have the tennis IQ/understanding of the game that can't be taught. He could potentially be a great player although he doesn't seem in the right path at the moment. Not to mention he just recently turned 20.
Goffin, on the other hand, is 22 and never even reached an ATP semifinal. He literally has one good tournament in his entire career, RG 2012, where he beat Stepanek, Kubot and Clement as a lucky loser after losing to my crap countryman in the last round of quallies. That's it basically. He never beat or even pushed any of the current top 8/10, his game is one dimensional and he can be overpowered in ridiculously easy fashion (not just by big hitters). In short, he's a potential good ATP player, never a threat at the highest level by any stretch of the imagination. He's just overhyped because he loves Federer. I'm not kidding when I say he literally never did anything else btw, not even a 250 SF to show for.
As for Rosol, a lot of people have expressed surprise/disappointment at how he failed to build on after beating Nadal, which would be completely expected for anyone who had any knowledge of Rosol's game. He was never like Soderling, who had the potential to be a great player and only needed ong big result to break through, his game is too erratic to ever be any sort of consistent threat or even a good ATP player, he just happened to redline his game in the right day to become a cult hero.
