The thing is (and I've said this before) its not necessarily his size, but for that height to play forward you need at least 1 exceptional standout trait.
Jack as an example is incredibly smart
Darling for example is incredibly strong
Curnow for example has an amazing leap
I'm not sure I see 1 of these outstanding traits with Bauer. I reckon he can make it down back, but unless he has an exceptional trait being smarts, strength, spring etc, I don't see how an undersized player can make it as a key forward.
