On CT he carries because his awp is insane, but his lack of aggression stagnates literally anything 100T want to do on the T side. Moving to sentinel allows him to continue locking down sight lines, and possibly even more effectively with sentinel util as well as the awp, while allowing a star, and more importantly more aggressive, duelist player to lead the T side.
I think that stellar/100T's gameplan is the root of that issue rather than cryo as a player. While cryo is not the best entry, their playstyle was focused on slow defaults into passive postplants which stole his ability to play more aggressive. In fact, the few moments of attack side success in the 100t v Sen was when they ran fast splits and cryo was enabled to pop off. On xset, cryo entried on ascent and a few other non-chamber comps and was pretty successful. His rifling is also criminally underrated. I think focusing more on training him as a entry in the off-season with an improved igl/coach is better investment than shifting cryo's role.
