Currently you have a league coach with probably some working level of how Valorant works. Mike probably is supposed to be there to fill in the gaps. But outside of a couple of set plays, this seems to be a player-run team. What I mean by this is on-the-the-fly type calling with minimal organized plays. The problem with this method is that it is player performance dependent. Since you are giving more control to the players in loose calling than you would in tight, organize set plays and you expect them to win their duels.
One of the important parts of this system is that in order to perform better, you need your players to perform better. Traditionally, you would see players rotate out of teams and new players rotated in. This has been the esports model for decades now. For example you saw this in EG's rise with the addition of Demon1.
This isn't happening on 100T. You've got people on contract playing for the team for long periods of time. So if this is the situation, so what?
Well in a situation where you are player-performance dependent and your team is on contracts, you can't switch people. Thus the entirety of your practice has to be on player development. So yes, you got the win against G2, a struggling team, but long term it can't work out because you don't have the expertise to improve the players.
