That's 21 years of Super Bowls, and those that will likely make the Hall of Fame make up 17 of those wins.
So what exactly is your point here?
Not every SB is won by a great or elite QB, your own list proves that. There are 4 guys on your list that are clearly not Hall of Famers, and last time I checked 4/21 is about 20%. So over the last two decades 80% of SBs have been won by HOF Qbs and 20% have not. Clearly having a HOF QB makes it a lot easier to win a SB, but you still have a 20% chance if you dont.
Now if your point is that every HOF QB wins a SB, that again is clearly not true. There are QBs in the HOF that dont have rings, it is not a requirement to be in the HOF.
So again, what point are trying to make here?
