Underrated and undervalued yet undeniable on their day. These blokes don't get the recognition they deserve but can single-handedly turn a game.

None of these players have ever earned an All-Australian cap, but their teammates must love going to war with them as some of the unheralded stars of the game.

Here are the 20 most underrated players in the AFL:

15. Brad Sheppard (West Coast)

He has played every game in the back line for the Eagles this season and is arguably the most underrated defender in the competition. Doesnโ€™t stand out, but he gets the job done week in week out. Averaging 16 touches a game, Sheppard's efficiency is enormous, going at 84% as a defender.
