If we're trying to be objective about Fedal here, then we have to mention that both players clearly benefited from the absence/injuries of Djokovic/Murray/Wawrinka and the lack of opposition from the "lost generation" which resulted in weak draws and an overall subpar playing field. This made both Federer & Nadal look a lot better than what they really are, boosting their confidence along the way. When a 36 years old can comeback from a 6 months break, after knee surgery and a questionable back, and then win a slam right away, it's both impressive and worrisome. If he can then take off for a couple of months right in the middle of the season and win another slam, what does that really say? Just how good or should I say bad is the current tour? Nadal has had a rough patch since his body broke down in 2014, tons of fans were willing to send him packing into retirement because he was losing early left and right for over 2 years, injuries were piling up, and then he suddenly starts making slam finals again, splits the slam victories with Federer? Did I mention both of these players are over 30 years old and have a ton of tennis mileage from going deep in every tournament they entered for the better part of the last 10+ years? Players may become wiser with age, but the inevitable physical decline doesn't magically improve overnight. Nadal is nowhere near the player he once was 10 years ago and neither is Federer. If the "lost generation" would've been strong enough, these 2 would've been pushed out the door and 2017 would be quite different.
Given their legendary status, with a Fedal dominance, you would think this would've been an exiting year for tennis, however it's been one of the most boring ones in recent years. As I said in a past post, tennis fans remember the epic matches, the long 5 setters with great shotmaking. Save for the AO 2017 final (which is a bit overrated IMO) and the FO SF (Wawrinka/Murray), 2017 really fail to deliver anything worth remembering, even if the 2 greatest players of all time won.
