There are currently 34 QBs in the HOF. 16 QBs dont have an MVP. As for passing yards, Wilson will have more passing yards then those guys you mention after this year except for Rivers(6th all-time) Wilson by the time he retires will have more passing yards then Elway & Moon. Wilson can possibly get top 10 all time in TDs this year. Wilson has 9 Pro Bowls, only 6 QBs has more than him. There is only 1 black QB currently in the HOF which is Moon. He has no MVP and no Superbowl. Wilson is also not too shabby w/ his rushing stats. Wilson had a good bounce back year compared to last season. If he can keep it up for 5 more years, he will be in the top 7 in most QB categories. Stats wise he should be a shoe-in for HOF. Personality wise, i think that first season w/ the Broncos really poison the well for his image. If he can get another decent bounce back year and the Broncos have a terrible season then he maybe be able to restore his image again. Then again if he fails/bench/traded and Broncos do good, HOF will diminished greatly.
You're looking at too large of a time frame. The game has changed since Sammy Baugh and YA Tittle's time. Running backs are no longer getting MVP awards. The last RB to win an MVP was Adrian Peterson in 2012. Since then, it's been all QB's. It's much more of a quarterback's league, especially over the past 30 years or so. So you need to shorten your time frame to get a good idea of what the unwritten HOF requirements for quarterbacks are nowadays.
Of all the quarterbacks who have played since 1990, there have been 10 who have been inducted into the HOF. They include Joe Montana (2 MVP's, 3 SB MVP's), Steve Young (2 MVP's, 3 SB MVP's), John Elway (1 MVP, 2 SB MVP's), Jim Kelly, Dan Marino (1 MVP), Troy Aikman (1 SB MVP), Warren Moon, Brett Favre (3 MVP's), Kurt Warner (2 MVP's, 1 SB MVP), and Peyton Manning (5 MVP's, 1 SB MVP).
Out of that list, there are just two quarterbacks that have not won at least a league MVP or SB MVP: Jim Kelly, who guided his team to 4 consecutive SB's, and Warren Moon, the first black QB to be inducted and who had an impressive CFL resume that was taken into consideration. Both of those QB's played at the earlier end of the rather arbitrary criteria I chose, in the 1990's.
As far as passing yards goes, just to crack the top 10, all of whom will have played in the 21st century, Russell's going to need about 62k yards by the time he retires (Rodgers at #9 is at 59k). Russell's currently at 43k, about one good season ahead of Kirk Cousins and Derek Carr...Yikes! He has his work cut out for him. He's going to need to average close to 4k yards/season for 5 years to catch up with the big boys.
And as I said, one has to look at the fact that Russell hasn't received one single vote for a league MVP award. It's hard to imagine a HOF committee being any more forgiving.
