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:

12. Stefan Martin (Brisbane)

With all the talk being about Gawn and Grundy for All-Australian, Martin has gone along his business quite nicely. Thee star ruckman averages 19 touches a game as well as 34 hit outs. He has had multiple 20+ disposal games this year which is very rare for a big man. The most underrated ruckman of the modern era.
