Cross Over, Kuroko no Basket Recommendations
Both series are about basketball as the main male character faces off against powerful opponents throughout their journey. Rivalries and relationship development among various characters are expected. And from those developments, the MC also learns more about the game itself. Recommended for people interested in basketball mixed with interpersonal relationships.
Another story about basketball where the main character joins an average team and keeps getting better. This is VERY similar to Crossover, so if you enjoyed that, this is a must read.
