I think it might be the orgs/coaches. The region has been recycling a lot of players and putting them into different roles on different teams in order to play the meta comps, which is super unfortunate because brazil is so talented especially with younger t2 players. They have a tendency of picking up players that don't fit on the roles the team needs, just to fit the meta. Heat was a great initiator, but now he's on a senti and the transition hasn't been great. Tuyz on loud is also struggling, and that was both before and after vinny was benched. I think orgs gotta bring in the new talent. We got evidence of guys like 2G (PXS, pryze, even Lz) plus rookies like cortezia/xenom/ luk xo are cracked. Havoc (is he still considered a rookie?) looks so much better because he's much more comfortable, sometimes unstoppable even on that neon. But even guys that have been staples of brazillian rosters like khalil, pancada, cauanzin, dgzinn, even heat last year, at their best TAKE over on maps. At their worst though, some of the teams they are on are horrible. I think MIBR did the right thing this off season, picking up two rookies and changing the entire roster. And the rookies just look comfortable on the roles. Im pretty sure in kickoff the reason they didn't play tejo/breach was for comfort, and they were top 3 in kickoff, one game away from Madrid. For Loud, i think they had bad days early on, and couldn't recover as time went on, but they are still scary. Furia, i have no idea what they should do. At everyones peak, they should arguably be much better than where they are. All things considered, they had a really good stage 2 run last year so maybe they are focusing on that. In the end i dont think the solution for the teams is "just pick up younger guys and plug & play." That won't always work, but let the teams develop with newer talent and see where the future goes.
TLDR: orgs/coaches need to do a better job picking up players that fit the roles the teams need or switch comfort comps for brazillian players. or cut the dead weight and rebuild with younger talent. developing players
