I'm not entirely 100% certain on this but I think Tony & Croady have upped their involvement this year with the club. Not that they weren't heavily involved before mind. However both Michael Steele and Mike Riley have both toiled and worked mega hard for the club whilst both have had health issues which is phenomenal really when both are retired.
I think this is merely a shift in the younger guys having more input and certainly with Tony now being the major shareholder effectively makes him the owner I'd say. However the knowledge both Mike's have is irreplaceable but it does take a bit of the day to day pressure off them both I'm sure.
