I'm wondering, are there any sports manga that feature ojisans?
This has set in my box for a while along with several others, but I said I'm going to get back to maintaining this and I will.
Anyway, if you look into sports manga you have a good chance of finding ojisans. While sports manga normally focuses on youths typically an ojisan will be a coach, commentator, or even a legendary athlete.
Some noticeable examples that I have included
Kataoka Tesshin from Ace of Diamond
In Kuroko's Basketball four coaches and one other character are ojisans. (I also haven't added all of them). They are
Kagetora Aida
Genta Takeuchi
Masaaki Nakatani
Katsunori Harasawa
Eiji Shirogane
The rugby anime All Out!! has
Komori Shingo
Yoshida Satoshi
Nanjiro Echizen from Prince of Tennis
Harlem Beat
Haikyuu!! also has a lot of ojisans in the form of coaches and retired players. So many in fact these are just a few noticeable ones
Ikkei Ukai
Fuki Hibarida
Tanji Washijo
Nobuteru Irihata
Takuro Oiwake
Tatsumi Osado
And those are at least in series I know. I'm aware of a few other sports series. Namely boxing ones:
Hajime no Ippo
Megalobox
And there are some other ones as well that I can't fully remember that might have ojisans at some point in them.
But I hope this answer is decent. Serious apologies about how long it took to answer
