You can't really say one IGL is better than others because they won more. Many other things matter as an IGL. You could take Dexter and put him on a team with Axile, BlameF, Simple, and Perfecto, and they'd win events, but he's not really a top tier IGL. Nafany has 2 top 5 players, while you have other teams doing pretty good with less. Snappi has maybe 1 top 10 player (who was absent for an event he made a final with) and Ence have been very successful. NIP have maybe 2 top 20 players, and that's stretching it. They also have a pathetic awper and a below average support, so you have to give credit to Hampus. Jame is also praised by everyone he works with for his calling. Nafany got found out quick and unlike the best IGL's he hasn't been able to change his tactics up to go back to dominating. I'd argue that he's on a similar level to that of Jame, Hampus, Apex, Cadian, and Tabsen. I also wouldn't say hes to far ahead of the likes of Glaive, Art, or even Nitro. I wouldn't call Electronic a better igl then Nafany, it's too early to see that and most people agree that a lot of the strategizing is done by Blade. But so many other IGLs do a pretty good job with much less then what Nafany has. Ence made top 2, Astralis and NIP made top 5, BIG won Roobet and make semi's in Dallas, Even Chopper deserves a shout out for the Major run from Spirit, although he had a lot of players with a lot of potential. And while currently Aleksib has been doing pretty poor, last year in OG he made multiple semifinals of top tier events with a roster that really never should've made it past groups. When people call Karrigan the best IGL ever it's not because he won the most, it's because of how successful each roster he's had has been. The TSM team had some big names we know today, but at the time they were rising stars. That first Faze team had a ton of Stars so you could argue Karrigan didn't have to do as much but considering what happened after his departure, he clearly had a very important role. Then what he did with MOUZ in 2019 was absolutely fantastic and showed that he didn't need the best players in the world to lead a successful team. Yes 2021 Faze was pretty bad, but I'd argue Karrigan was just waiting to get Ropz so that doesn't really count. A truly great IGL is someone who can make a good team out of any pieces, and doesn't just need the best pieces for the team to be successful.
