I don't have a team, am I cooked?

So I'm an old player, I recently came back, breezed through the challenge and got 15 wins, but the problem is my stats aren't that great.

I have 3 and a half max brawlers, 29k trophies, and 15k 3v3 wins. I never played ranked, and the highest I pushed any brawler was 1000 this season.

Is there any way to get a team with stats this bad?
