why doesn’t zhang zhanshuo get more hype, he has been and is the real deal. also equivalent talent to Luca, especially with his 4 IM in 2023, AND luca has yet to realize the LC potential and match the 3:42 (albeit he’s a year or too behind and almost definitely will).

Hopefully he’ll be healthy during the meet of the year for the next few years.

His swims are always exciting to see.

Palpatine is a troll. And not like a relay names troll who provides legitimate opinions but they’re just awful, just an actual troll who has never written a genuine comment ever and tries to rage bait.
