Uh, everything he wins is legitimate, just like how all of Djokovic’s wins against old Federer are perfectly legitimate even if you have this age excuse.
Of course, one can call the strength of a tournament in question when a player hasn’t played a top 10 player, gets a literal bye to the final, among several other things, just like fans of other players have to listen to same old age crap ever since Federer started losing a bit more. And then of course, when Fed wins tournaments, it’s a huge impressive feat, the dude’s apparently like fifty playing in a wheelchair, when he’s obvs decimating his pathetic opponents
That’s how life works, Fed can retire anytime he wants. He hasn’t yet so he’s held up to the same standards of every other player, every tournament he wins can be questioned and the strength of the players he faced can be debated.
As I said, you can have the IW title, but this tournament was totally pathetic. I’m simply calling into question Fed’s ability to win tournaments with strong draws. He does so sometimes(Miami 2017), other times you have this tournament, AO 2018, among a litany of many others
