I think this would be quite a good trade/signing for LA and quite realistic.

Reasoning for each player:

John Collins - He would be a good upgrade over Rui hachimura, they both play similar roles but John Collins is more athletic a better defender and plays more physical leading to more rebounds. Rui is a better 3pt shooter but John Collins had a great year shooting 39% from 3 so it wouldn’t be that much of a difference. Only downside is the contract but it does expire in the 2026 free agency. We’re currently seeing a certain type of power forward that is needed on championship teams, like Aaron Gordon for the nuggets and obi toppin for the pacers, John Collins could definitely be that type of player.

Kessler - The perfect defensive big for LA. He rebounds, plays great defense and is young which means he can play with Luka for years to come.

Jake - Recently he was spotted hanging out with Austin reaves and Austin reaves said he would put in a word about trying to recruit Jake to LA! This would be awesome as Jake is 23 and has a great play style that fits with Luka. He’s a 40% 3pt shooter and can play good defense, he would be a great replacement for dalton as they can play similar roles and they’re the same age (almost)
