It's a very close debate right now as I think Djoker would win at Australia and Rolland Garros while Sampras wins at Wimbledon and US Open. For how great Djoker has been his Grand Slams finals record of only 13-9 is bad while Sampras was 14-4. Obviously Novak showed he's not done winning slams and I'm pretty confident he will pass 14 in his career, how high can he go? Imagine all 3 of them ended up with 20 Grand Slams
I think Federer has just not been able to close recently for some reason. He had match points in his last 3 losses but just couldn't convert. I can't wait for Rogers Cup to see how they all look on hard court.
Right now odds makers have Djoker as the favorite for US Open, then Fed 2nd then Nadal 3rd. Shapo at 33-1 might be worth a $20 bet
