I am going to ask this again: what exactly has marin ever done to be so widely hated?
his oncourt behaviour is not rude or disrespectful
he's never said anything offensive that i have heard
he might be a mental midget but who isnt these days?
his game isnt boring to watch
he's very good with fans
I, of course, don't hate him, but he is an emotionless player most of the time, and that's boring. Also, his game is more or less one-dimensional. While he could use his height to get a decent serve, and eventually go to the net after it, he decides to stay at the baseline and get in a long rally, which more often than not he finishes with an unforced error.
And yes, he should get rid of the monobrow.
