Only sports anime I've watched so by definition its the best and worst I've seen.
I don't watch lots of sport anime but Megalobox was great. I'm currently watching Initial D and I love it so far so if driving count as a sport, I'd say it's potential favorite sport anime for me.
Recently I enjoyed Harukana Receive, mainly because watching Haikyuu!! made me like volleyball xD
really enjoyed MegaloBox and Big Windup was a guilty pleasure
i second megalo
and raise a haikyuu
ballroom e youkoso
run with the wind
wait i mean
and yuri on ice
i love the trend of alternative sports animes
ill also recommend hikaru no go, a really good anime/manga about the game Go, but its really good (if esports is a thing then do is japanese chess)
I hate basketball but Slam Dunk is good. Other good ones: Knock out,One outs,Major,Megalo Box and Welcome to ballroom.
Ok did someone said Slam Dunk? Good taste!
