That is really a tough one considering the issues you've laid out. Not to mention that I doubt either team will be particularly good over the next few seasons. As of right now, i'll say Rinne. He is younger and has alot more potential to be a very good goalie. I think that at this point Bryz is what he is. He may have some above par seasons, but I think that while he is the goalie of the Yotes, he is limited on what he can/will do. He will not be as good as Rinne overall, imo.
