WHO DOUBTED THIS MAN
Even as someone who watched carpe in owl and knew that he had god tier mechanics (there are tales of him doing sub 100 reaction time shit on human benchmark type insane levels of mechanics), it was more just uncertainty surrounding the pickup.
They decided to pick up a player who has no real experience in the game that may or may not pan out, when you have other options available to you that are like proven to be able to close to that level I would think.
It was just a really big risk from T1 to sign him because his potential is higher but at the same time he could bust through the floor and mess us their season if he doesn't turn out to be the player you expect. But it's seeming to work out pretty well for them as he has clearly improved to becoming a player that can play at that level rather than just a liability.
