This really shouldn't be a debate. Kohlschreiber, who has been playing the tennis of his life in the 3rd round. 4th round against Soderling who is playing out of his mind and went to the Roland Garros finals. Quarters against Tsonga, AO finalist, or Verdasco who knocks the yellow out tennis balls, or Karlovic who has the most effective serve on the ATP tour. Now, you may pull for another player and see their draw and think in the back of your mind that they have a tough draw, but don't lose perspective of the caliber of the players. With all this said I fully expect him to handle every player he faces.
