I would bet that Sidey, Amir, Chakra and Cookie could win that game 4v5. Each of them is better than anyone on the 2nd team, with the possible exception of Cookie. However Cookie is very good at building a lot of farms and not dying, which is all he has to do here for his team to be invulnerable. They may have some difficulty wolfing, but I could see them lasting the full 20 minutes quite frequently. Hawkys puts them over the top, and acts like an insurance policy. That team could make a major f*ckup and still win.
BW is kinda overrated, especially in consideration for a long team massing game. Also Chaise died in 30 seconds while he was at his peak. So I feel like you're redefining "peak" to mean doesn't make any mistakes.
Chakra really is beautiful. Like all westies he's underrated for being modest and for not playing a lot of revo, but at his peak (which came quite late) it would be hard to distinguish him from the best player.
