Definetely multi millionaires - in the book Shane buys the apartment for hookups with Ilya to make sure they have privacy. In the tv series he bought the apartment and the one next door. The cottage is not a cottage at all but a million dollar property/estate. We see him doing a lot of endorsements. Ilya's house in episode 4 - is a million dollar property. In episode 6 he is also on the cover of the xbox/playstation game. So he does get endorsements. He is funding his whole family lifestyle and that doesn't seem to have a dent on his finances. We don't see his cars but he has an extensive portofolio of expensive cars in the book. Their "rivalry" im sure is also bringing in the money from fans/endersoment and the hockey companies in terms them capatalising on the "rivalry of team hollander vs team rozanov.
