I actually e-mailed Adam just after the Oilers released his rights. The Oilers decided to sign Mike Morrison instead.
Morrison is terrible. Hauser was on a winning Frozen Four team a few years ago. Supposedly he was not that technically sound but played hard and relied on determination to even get to NCAA level hockey.
We have J.J.D. and Conklin now, so not signing Hauser turns out to be no big deal, unless he can actually make an impact in the NHL.
