I've heard a few people mention Taylor Adams' height as a concern, to the extent that I decided to check to make sure I hadn't overestimated his size, and nope - Every source lists him at 179cm or 180cm.
Leigh Montagna, Sam Mitchell, Jack Steven, Mathew Stokes, Chris Masten, Tom Liberatore, Dion Prestia, Dan Hannebery, Kieran Jack, Steele Sidebottom, Brent Harvey, Adam Treloar, Nathan Jones.
What do those names have in common? All 181cm or under, all finished in the Top 50 in the AFL for average disposals in 2013.
In the role that Adams plays, height is not really that big of a factor, and even within that, he's not shockingly short, and when you consider that he's quite strongly built, it really is pretty unlikely to hold him.
