Rec a sports anime series for my mom?

So my mom has finished watching all of Prince of Tennis (she didn't seem surprised at all by the ending) and she doesn't want to watch any of the OAVs because they don't really finish their story lines.

Can anyone rec another series for her to watch? 

She likes:
-silly, unrealistic stuff (eg: she likes Yowamushi Pedal and doesn't like Haikyuu) 
-finished series

As much as I would love to give her Slam Dunk, I think it would be too slow for her. :(  

[Edit] I forgot the mention that she has already seen Kuroko no Basket!
