So how about i use your logic. In 08, Federer played like garbage, had nothing to do with Nadal, in that RG final. In 07 final, Fed won first set 6-1 in RG finals and had a mysterious letdown and let nadal nada l back in the match. In 13 semis, Djokovic missed an overhead, easy shot... to go up in 5th set, he was already up.... Nadal was lucky. In 14 semis, ferrer took first set off Nadal and took gas off the pedal... let Nadal back in. In USO final, Medvedev should've won that match vs Nadal, med better on hards, just was weak mentally. Thiem was tired and washed out in 20 RG final after that 5 hour battle with Djokovic in semis.. Thiem had opportunities... let them slip, took a set off.. if he only wasn't wasted and tired. Stan played scared and HORRIBLE in 17 RG final... no way he loses like that to nadal, he had won RG year before, he choked!
We can play this game all day long because it's very easy to do. Oftentimes, one player looks bad because of the opponent's play. The opponent is part of the puzzle... Medvedev cannot just play the same way he played against others, vs an in form Djokovic. Neither can any player play comfortably in the zone tennis vs Nadal at RG. Remember, 9 AOs and 13 RGs, for A REASON.
We can point to a ton of missed opportunities and bad play by losers... Federer squandered a a high # of break points vs Rafa in some RG finals. You say, 'Nadal too good', cali would say 'Federer a mental midget and WEAK'. It's all to do with our biases... you clearly don't like Djokovic, cali hates Nadal.
it's just very easy to point to a bad point here and there, a missed break point here and there, how they look vs how they looked vs others... this is just easy stuff, we can all do it. The problem is stats and facts don't lie. Remember rafa in 19 AO? He DESTROYED Tsitsipas... then how did he look in finals? The complete oppopsite, USELESS AND ABUSED by Djokovic. Did Nadal, who is extremely mentally strong, just happen to summon his best vs Tsitisipas but choke in finals? the difference was Djokovic... not Nadal playing poorly.
NO-ONE is going to look good vs Djokovic in AO when he is in top form... NO-ONE. Stan may be the exception but Stan has a very powerful game where he can take racquet off Djokovic. Meddvedev can't do that... When Djoker is at the top of his game, Medvedev is going to look bad. Djokovic has even made Federer look pedestrian at AO, in 16 those two sets 1,2 vs Fed, Fed looked like a college player... When Novak is striking ball well, serving well.... and not missing, sorry, medvedev is outclassed, so is nadal, on this surface, at AO. When you are facing Djokovic, you will have times when you will get discouraged because Novak's game is too tough.... yes there will be some downs... same with nadal at RG. The question is why? It's Nadal and Djokovic doing this to opponents...
