I think SEN really does need an assistant coach as well. (should take some inspiration from TH with the amount of staff they have for players)

oh did not know about that, well there is just no upgrading from sacy or zellsis i suppose then. Maybe verno or narrate instead of sacy.

they can always keep him as a content creator, he is good at it

• TenZ (smokes/flash ini)
• Zekken (primary duelist)
• JohnQT (igl + sentinel/viper)
• Sacy ( scan initiator + mid rounding)
• Patitek/Forsaken/D4vai instead of Zellsis

Patitek/Forsaken can literally play anything , and be your secondary duelist if needed, a perfect 1 to 1 replacement for zellsis with better mechanics.
It is just tough to replace Zellsis because he plays so many agents. Kj,breach,brim,viper, kayo man is all over the place and a vibe merchant with mid rounding as well.
1:1 replacement for sacy as scan initiator is doable but Sentinel's mid rounding will suffer a lot if they just replace both.

More suggestions are welcome, without shitting on any player.
