G.O.A.T.
I agree overall. As for your last paragraph, yes Novak read it better, but Fed def. also served worse. Both percentage and precision wise.Federer just dropped 11 points on his serve in Wimbledon Final. One can blame this on unusually higher first serve % from Roger but in second set of Wimbledon he served close to his average 61% and yet Murray couldn't even produce a single BP. Federer won 100% first serve points in that set and remember Murray was supposed to be fresh in that match. Today Federer served 55% which is little below his average and yet Murray couldn't produce a BP again. Let's say, Murray was exhausted but what special he is doing when being fresh? Nothing.
He is struggling to win points on Federer's serve lately and as a viewer without looking at numbers, I feel his own failures to read serve contributing it rather than exhaustion or something. Just see the difference between his and returning of Novak's in Wimbledon. Djokovic seems to read his serve way better while Murray had no clue.
Yesterday's failure on 2nd serve was more a matter of Murray failing to read it properly (hence the many unreturned 2nd's) than him being too flat to react to the comparatively slower 2nd serves. His win percentage vs. Fed's first serve was fairly standard for a fast surface.
