I feel like while NRG went 0-4, all of the maps were winnable if they didn't make some really obvious/avoidable mistakes. maybe the only map I thought the firepower was genuinely their main issue was lotus against sen. the rest they just kept making clear mistakes, for example on haven against g2 they let leaf walk into garage every round and they somehow still kept getting caught off guard by him (partially a comp issue, but he wasn't even catching some insane unavoidable timing).
chet got a lot of hate for the haven comp, but I thought it looked promising. on another day, victor doesn't get first blooded like 3 times on defense and they win one or two more rounds. but even ignoring that, a lot of their utility timings on both attack and defense were a second or two off from each other which is something that inevitably improves with more practice (the set ups themselves were good imo, which chet likely came up with). FNS also had a horrible performance even by his standards.
a more general issue I have with the team is that they're too "disciplined", they have a game plan and they stick strictly to it with none of them trying to make any plays even though they have a very good opportunity to do so. for example I feel like TH and gen.g have good game plans but their members aren't scared to do their own thing sometimes, meanwhile NRG play exactly by their protocols and it's impossible for the protocols to work 100% of the time (especially not in this meta)
anyway I think they COULD beat kru and c9 4-0 but they're definitely not doing shit in champs even if they qualify. all these simple mistakes aside, firepower is still an issue so I don't see them keeping up with the very top teams like heretics and gen.g but they could definitely be top 8 if they fix their issues
