With all his arrogant post match bullshit hes said over the years.. How did he even win it once?
Granted he has said some wrong things in his interviews. However, I think this award relates to fair play on the court. And that is where he triumphs over others in my humble opinion. He does not allow any time wasting, celebrating over unforced errors of opponents or offset the opponent in any manner, sort or form. He just plays tennis , plain and simple. This might be the catalyst to him winning the award multiple times
