you dont replace anyone they got a perfect team they just need an assistant coach or an analyst that can bring in some creativity to this team and help them create some setplays they could do/a gameplan they can fall back to instead of their current ideology which is mostly based on reacting to the plays of the opponent (rn as far as im aware the team is only the 5 main players and mike as headcoach and ddk as gm)
also good to have another person for their coaching staff so they can increase the vod reviewing potential
you might think of replacing cryo with another star player.. but they really isnt a free agent thats better and cryo isnt bad 100t just isnt setting the plays centered around him so it makes it look like hes performing lower than expected (obviously his oping could still be better than what weve seen so far but everyone has bad days)
