Seeing them in Macau, I don't think they are properly match fit. At the moment, I don't think they will win.
I don't think its just a case of being match fit, I just don't think that as a pair they have what it takes to beat the minions. LYD is actually still playing a pretty solid game, his serve has improved and he is starting to find his groove. But he is a lot slower than his old-self. Although I think LYD himself is still capable of beating the minions, he needs the right partner with the right attributes to do it and I don't think KJG is that person.
The biggest weakness in this pairing is the lack of a strong effective attack. KJG simply does not have a good enough smash to bring LYD into play. It is neither strong enough or accurate enough to consistently force a weak shot. The minions will just soak it up all day long. Their counter attack and defence is pretty decent but you can't rely on counter attacks and defence all the time, especially if your attack is not that effective.
KJG is also quite slow now, he has noticeably put on quite a bit of weight and seems to struggle at times to sustain a strong attack. I think KJG (and LYD) need to make better use of their smash by going for the side lines more and mixing up the placement of their smashes to try and create openings. Their smash to the body is also a bit too low, which makes it relatively easy for opponents to return. I really don't understand why LYD, after all this time, still insists on smashing straight, at his opponents racket arm, time after time. It does not work and he will tire out. I know that this is a reasonably safe shot that does not expose him to counter attacks so much but if it does nothing, what's the point?
The other thing is, I think LYD really needs to take a leaf out of SBC's book and start to fake some of his net skills/drives with some drops. SBC is so good at generating short lifts from these.
They also need to be careful about their blocks back to the net when they're out of position as the current generation of MD players are quite good at reading this and it's becoming quite obvious when he's going to play them.
Well, I hope LYD/KJG can prove me wrong, like they did against Sonoda/Kamura.
