Eyeshield 21, 15: Meisetsu Kougyou Koukou Rugby-bu Recommendations
Both of this mangas are about a guy with a hidden talent that is discovered by another person who have high HIGH goals. Meisetsu is about rugby while Eyeshield is about American Football, and unlike Eyeshield Ebina, the guy who discovers Akira, is not as evil as Hiruma, but these two people aim higher than any other person and have a very strategic minds.
Akira and Sena are very common for they don't really have any friend before they join the clubs.
This two mangas are very similar because they are about a team sport, friendship and trust between each other. So far Meisetsu seems really cute
