Assume you mean his chances with the two FaZe lineups.
Took a lineup with no direction and made it a playoff maker, it was a fluke of a bad tournament in first FaZe (With karrigan) and the lineup could've had a long future if they hadn't revamped to super star after that major. Speaking of...
Second FaZe (With Karrigan) was legendary, he proved he could lead the squad and if he had won the Boston major likely would've gone on to create an era where Astralis did. He already had a good start on this one. It didn't end up working out, rain slumped, GuardiaN slumped soon after Katowice, olofmeister slumped to the point of leaving, NiKo stopped respecting calls. Even within the shittiest situation an IGL can be at still managed the only 2-0's on Astralis until the ENCE 2-0, managed to be the only team to 3-0 Astralis in their prime, managed to be a consistent top tier contender even missing one of their stars.
mousesports, it was only a few weeks and analysts were already calling it out to be an immediate Top 10 level team, many people after seeing them in action calling for one day to be Top 5 potentially, I think that's jumping the gun but still. It's a new kind of challenge and karrigan is still adapting perfectly.
Mousesports won't cut the roster if there is a fluke of a tournament, they won't have players who have balls big enough to question karrigan as an IGL, and they're a roster stacked with talent. Frozen is quickly becoming one of the most developed rookies we've seen very quickly.
People say it's a pattern but first time it was FaZe as an org, second time it was the players not being able to be confident anymore. The chemistry evaporated after a really hard loss on the team followed by more hard results.
