Okok, on a more level view, LCW's injury seems like a 7.5/10 to me, his first set (at least before first interval) with CTC in SF and SYQ in F were quite relaxed, playing a very courteous "giving up initiative" clearing/lobbing game and all. That reeks of him wanting to warm up the body and test his joints before fully entering into condition. No longer the all guns blazing LCW from years past.
This past AE gives me the impression "If he can stretch to get a down the line smash, he would, if he can't, then whatever, he'll give it up."
Especially the one cross court smash that SYQ returned, LCW didn't even bother to run the full diagonal from rear backhand to front forehand corner to retrieve, that was quite obvious IMO. And it shows that mentally he can afford to lose 1-2 points here and there. Netkill that cost SYQ his ankle was another somewhat, but that's subjective. I really feel for SYQ there, having had that happen also. I cringed when I saw that.
TBH, SYQ winning LD may be due to the fact that LD doesn't inject pace suddenly these days, preferring clears and drops while LCW is one that will still jump smash at an opportunity. And the fact that they train together means he somewhat knows LD's game, even if a fraction of it.
On a side note, he finally gives up his bloody SHB92MX that he's worn for what, 6 coming 7 years?
