There was not really that much of a sign tbh. In pugs and when he played for ex-mad lions then Masonic he looked quite mid. Glad he's doing well though seems like a nice kid.
His FACEIT says he started in 2019 but that's still absolutely insane.
Just think about it, he started playing CS when Astralis won their 3rd major, and now he's playing there.
His first match in FACEIT is in 2019, checked it on Faceit finder. Didn't see that his acc is created in 2015 so that's interesting.

I think thats not accurate. For me it also shows first match 2015 even tho I started 2013.
Also I have played with Buzz long time ago and I think it was before 2019, or maybe I remember wrong.
Also it doesnt really make sense to make an account in 2015 but play your first match 4 years later. But anyway at the minimum he has played csgo in some form in 2015.
