He's bulked up like crazy, looking like the hulk. He's turning into a Karlovic where he can't actually move fast enough along the baseline to where he can actually use the power he possesses. When he actually gets into position to hit balls, he can crank them, though. Milos can't serve and volley very well, either; he needs to slim down for longevity. He's not going to win matches at 230 pounds from the baseline -- even with a wicked serve.
I'm sure he'll get back on track. He has a lot of discipline and confidence.
