Technically you're right that at this moment its a big 3, but over the course of this year it has been a big 4. I kind of agree. part of the reason why i started liking djokovic in the first place was because he was the only player apart from federer who looked like he could be a consistently good player who played fairly attacking tennis. Not as much as federer but still way more than Nadal or Murray. sadly djokovic has become more of a grinder, almost as much as Nadal and Murray. though their matches can have amazing rallies its just too much of the same after a while. nothing like the beautiful tennis if federer. best match ups are fed vs djokovic or fed vs Nadal. when its Murray/djokovic/Nadal vs another the one dimensional nature becomes a bore. impressive but not something i would watch again. Murray has gotten a bit more attacking now but the speed of courts mean its still a challenge to hit a winner past anyone.
