Sorry for the late reply but I watch the tennis before I poast, unlike many.
I love Coffin's style and watch plenty of his matches, including all of them with PCB this year, whom I also like. Like you said, they're simply not going to win any tournaments facing decent competition, so I don't get too excited. When players like that play each other, like I said the battle for 5-30 in the rankings, they all know they're never going to win anything serious so they play freely with little pressure. The matches usually end up being pretty high quality, but as soon as they win through to play the kings, they implode.
Grigolo and Guru are absolute f***ing clowns and you know it. Surely you trolljest about Jisner and tall-short-slow-man Gasquet? You can @ me about some performance here or there by Grigolo or Guru but that's the point - they performed at their potential when it mattered what, once, twice, and lost anyway? The rest has been smashed racquets and 720 degree smashes. They're even worse to watch than Coffin and PCB. PCB's ground and all court game is criminally underrated but his serve is also criminally underdeveloped. If he gets his serve sorted, watch out.
Berrettini is a mentally tough Sock. The BH is the fatal weakness there and there's always someone around who likes to play topspin to the BH, no? Fog would be a very interesting prospect at WTF because he can beat anyone except Fed, but he definitely has some leg niggle. I think Fog's fitness is the only reason Murray was even partially in the match. Murray isn't going to be top 10 again, not even close. And he's made no real adjustments or developments to become a better attacking player (or any more watchable).
Fed's coaching of the Rot at Laver Cup did seem to backfire on him but Zed is still not a threat IMHO. He lacks the utter bottomless pit of self belief and defensive touch to be king. That could change, but sitting 2-3m behind the baseline and hoping to blaze his way to glory isn't going to help. The muscle comment was a joke about Zed's comments all through the year about all the work he has been doing, seemingly working on every muscle except the one that matters... But you're right, watching drowning desperate Rot writhing around snatching at points is good, possibly the peak Rot experience. This disaster recovery mission will definitely help his character.
Speaking of drowning men snatching at points, I used to be a Thiem fan too but he has just been too stupid for too long. He is too slow on the takeback for groundies - all the other problems flow from that - he needs a full rebuild of the FH at a minimum and maybe some major work on the BH too. He has also allowed too much scar tissue to be built up with big, soft losses to the Nadal. He has lost half a step already, without a physical injury - burgers IMHO. He is damaged and he knows it. I think he's too far gone and can only come back after really feeling it for a few years watching lower-powered players succeed.
Remember, pretty much everyone who has succeeded during the year is tired by this stage of the season. It's no coincidence that the players winning now had pretty slow starts to the year (Med) or were injured. There's only one player to have a genuine career-defining run late this year and that's Med. The rest is just noise.
You've also got to ask yourself, what kind of diamond age is this? What kind of Diamond Age do we want? Diamond Age Minor League? Diamond Age But Only BO3 kthx? We want all courts, all surfaces, open, BO5 no ****ing around Diamond Age. That means recreating your avatar, time after time after f***ing time until Fred, Noel and Ralph just give up and go back to Switzerbiapain.
Right now, Noel is 100% tanking. Whether it started at the USO or after is open to interpretation, so maybe poast-USO. It looks like he has written off the rest of this season. Maybe Ultron shows up at WTF, maybe not, but AO20 will be a verrrrry different story for all of them. Have a look at that AO19 final again. He'll be right there waiting for them with a smile and a heart throw, whichever bright young thing comes crashing through the door on that fateful Sunday...
Med can have his little stares down the court after dusting off Sissy and Rot in BO3 Masters nonsense, but let's see him at AO20. As far as I can see, Ultron has only two weaknesses: returning non-stop 1st serves and reading OHBH DTL at 80+mph. GLWT.
There was some good tennis in Tokyo-Beiijing-Shanghai and they tried so hard and got so far, but in the end, it doesn't even matter...
