Him being the top fagger of the team (which he isn't) is not enough. If it were, Na'Vi would be the greates team of 2018, 2019 and 2020 and that's not the case. His kills means little to the rounds won, whilst even TACO's frags as low as they are means more to context.
balerostyle doesn't have experience with PRO teams but on amateur championship's he's quite a winner and that requires consistent teamplay, some teams included felps to that matter. Recently they've created a team for a gamersclub cup and won while being the only amateur team on the entire championship, against pro's only.
In my opinion any good player can be modeled to play within a team, given the right styles involved. If the style is the right one for that strat is a whole new topic.
Also by that matter, Stewie2k, s0m and many other good players came from this exact beginning.
