Check out the Cultist Club in the forums for Manga that are little read, but much appreciated! These are the club entries I endorse.
Some manga are worth one or two reads, and then there's some that I can never re-read enough. These are my picks.
Plan on reading these series and eventually making a top sports manga list.
A handful of the manga I am going to buy soon, (Personal Note: refer to MAL + TM shop for others)
Mangas licensed in English that I want on my bookshelf someday.
Shounen on my want-to-read list.
