the argument of "but his aim is worse now!" - yeah, if you've actually watched the games, you see he frequently tries to overcompensate for his team by peeking far more aggressively than he's used to, which either means
- he's being told to play more aggressively and take duels, or
- he doesn't trust his team to get the frags, so he forces unnecessary duels, leading to gunfights where he's 'disadvantaged' compared to OPTC who set him up for every single play, building their gameplan solely around him
his aim is definitely not what it used to be, but like I said, that can likely be attributed to being in uncomfortable positions and losing confidence in himself because he doesn't thrive in those new positions. if he got tossed back on a tier 1 team who set him up properly, who knows? he might still be shit.
but it's foolish to say he's just bad now - going from dunking on every team in the world to whiffing against lower tier teams doesn't randomly happen
