Everyone is entitled to their opinions. However- let me ask you this: How is Tipsarevic (and to a lesser point, mugaco) be good for the game, when the TOP 8 seeds are literally walkovers? Imagine- if in the next year Nadal and Del Potro will be out of the Australian Open- The top 8 seeds would be 6 good players, with Tipsarevic and Monaco. The serbtards like Tipsarevic not only because he is Serbian, but also because he is literally a walkover for the top players. Djokovic gets Tipsarevic in his quarter, while Federer gets Berdych.
How can someone like Tipsarevic be good for the top 8, if he cant even beat Raonic in Chennai, or Isner who is an atrocious mug himself?
Also, another idea: Tipsarevic was the 8 seed in the 2012 USOpen. Lets look at previous 8 seeds at previous US Opens, and determine who is the better player out of these guys:
The only player who Tipsarevic can have an argument against is Fish. And even Fish is a better 8th seed, because he has several Masters finals, when Tipsarevic has 2 MM titles.
Hope that gives you something to think about
