Yes it is. He should have won the match, and would have if he could have been Serverer for a few of the games.
Woulda, coulda, yadda yadda... and I could say Nole would have won the match more easily if he hadn't made twice the errors he usually makes. He gifted away many many points just like Federer. That someone has an early break means absolutely nothing. Actually the pattern of federer-djokovic matches has been now reversed. Before, when Nole was the younger and most inexperienced player, their sets would be pretty even until 4-4, then Federer would usually take advantage of his experience and break Nole in the next game to serve for the match. I've seen this happen countless times. Now Nole is doing to Federer what he did to him while he was the younger and inexperienced player. Cycle of life.
