For the record Kang Kang did do this today, dash into a point that is, but I already mentioned earlier he got instantly contested and killed because T1 already know what the hell he's going to do and are ready for it, Split is not an easy map to just 5 man default on, that's why you see a lurker always on A. So what happens next? Rely on trades? Their trades have looked completely ass this series except for Fracture so their confidence in that is also probably quite low, not to mention iZu playing Yoru means he gets out of jail free so he can't even be traded, and it doesn't help that they got steamrolled on bind, their OWN map pick. So recklessly do the same play again till it works? Of course not, they have to switch it up somewhat, maybe get a pick somewhere to increase chances of a successful site hit. The reason why I mention the problem being the team entirely and not just him is because they should know he wants to go for an earlier gunfight at mid round start for an easier site entry (heck they should know exactly how Kang Kang wants to play memorized) because it's quite literally right at the beginning of the round, but that's not what it looked like today at all. Throughout some of the rounds, Kang Kang did not start close to the site hitters and on the rounds that he did, they got absolutely destroyed by T1 so this probably forced him to think of something else. While Kang Kang was hunting for a pick, his team was prepping for a site hit KNOWING (or should know) their duelist isn't with them and that he would be late to come for the exec. Is Kang Kang at fault for his weird positioning? Probably. But it's also the team's fault for knowing this and still executing like normal. Then the rest is just them throwing one by one as a result of the fumbled rounds. Smoggy tping in before util and Nobody peeking with a drone still in his pocket.
If Kang Kang isn't dashing onto site or whatever instantly, that probably means he doesn't think it will work if he doesn't get some sort of pick first (even if the trades go in their favor) which you can really only get with a read on what the enemy is doing or have good info on where everyone is, otherwise that's just gambling that Kang Kang is good for one.
Then eventually we've got EDG's defense rounds, which IMO is what your post should be more focused on instead. He got 0 on Split defense, going for hero plays and one and done spots that even a Jett can't get away from making him almost untradeable for his teammates.
