There's no way SEN doesn't renew him, right? He had some personal issues but still one of the best players in the world imo.
Even if they let everyone's contract run out they'd still need to inform those they are not considering for 2023. That's why I think the roster might not change and they'll just add a controller. The only thing I think will change is the coaching staff and as much as the coach would want to pick his/her players, that probably won't be the case with this SEN roster.
Esports is literally a deficit business. But this SEN team makes a lot more than any other team out there if you compare them roster for roster. It just doesn't make sense dropping them in bulk.
