In the age of Bellicheck it's a tough bar - multiple SB appliances, multiple wins, but he is an anomaly.
Mike McCarthy, Sean Peyton, Andy Reid. Mike Tomlin - all coached for many many years (some with the same team). All have a total of one SB win each in their careers. These are the top echelon coaches in the NFL.
With McVay I think we have a very good coach, who runs the team the right way and I would suspect we'll be in the playoffs many years to come. Maybe one SB trophy in there would be nice but just that we're competitive year in and year out and have a shot every year is a vast improvement from anything the Rams ever had in coaching.
