2-3 years. ASP gets pushed away too easily and skating needs work, Europe is the best place for ASP next season. SHL, CHL, U20 Worlds and maybe even some men's national team games too, lot of games to play next season. There is no reason to rush him, during this season ASP was playing the second fiddle to Pudas. When ASP beats him for the job, then he is really ready.
Ray made the team because Vrana got injured, it would require at least 3 d-men to be injured at the start of next season in order to ASP be in opening day roster + dominant camp. And ASP is a pro already, SHL is a pro league.
