Getting to and Winning a SB is a team effort... But the fact remains that the most common denominator in doing either successfully is an elite QB / Coaching combo... It's pretty evident when you look at the list of every SB winning team... Then look at who was the QB / Coach.... It's like 80% All-Time great QB / Coach combos.... and a handful of outliers. So it's far from irrelevant... It's like 80% the determining factor.
