There is no real convincing case to put Eli in the HOF other than the odd fetish NFL fans have with winning one game in the shortest playoffs in sports. It's bizarre that that carries so much weight (enough to make a top-10ish QB of all-time like Tom Brady get talked about like he's a #1, for instance...same with Joe Montana, who is probably a rung up on Brady, but probably not top 3).
There's 28 QBs in the HOF. Let's examine some of the "worst" and compare some things statistically to Eli...
Eli Manning
2x Super Bowl MVP
Never First- or Second-Team All-Pro
Top-8 finishes in passing yds: 4, 5, 5, 6, 6
Top-8 finishes in passing TDs: 2, 4, 4, 4, 6, 8
Top-8 finishes in comp%: N/A
Top-8 finishes in int%: 7
Top-8 finishes in QB Rating: 7

Joe Namath
1x Super Bowl MVP
1x AFL Player of the Year
First-Team All-Pro: 1968
Top-6 finishes in passing yds: 1, 1, 1, 2, 2, 3, 6
Top-6 finishes in passing TDs: 1, 2, 2, 2, 4, 5, 5
Top-6 finishes in comp%: 2, 4, 4, 4, 5
Top-6 finishes in int%: 3, 4, 4, 6
Top-6 finishes in QB Rating: 3, 3, 4, 4, 6
Some asterisks here as Namath played his first five seasons in a split-professional setting.
Troy Aikman
1x Super Bowl MVP
Never First- or Second-Team All-Pro
Top-8 finishes in passing yds: 4, 8
Top-8 finishes in passing TDs: 3
Top-8 finishes in comp%: 1, 2, 2, 2, 2, 5, 8
Top-8 finishes in int%: 1, 2, 8
Top-8 finishes in QB Rating: 2, 3, 3, 5, 6, 8
Terry Bradshaw
2x Super Bowl MVP
1x NFL MVP (+ 1x Bert Bell Player of the Year)
First-Team All-Pro: 1978
Top-6 finishes in passing yds: 3, 5, 6
Top-6 finishes in passing TDs: 1, 1, 4, 5, 6
Top-6 finishes in comp%: N/A
Top-6 finishes in int%: 4, 6
Top-6 finishes in QB Rating: 2, 5, 6
The goal of the HOF isn't just try to fit people under a given low bar by rationalizing and compounding previous mistakes...which Aikman, for instance, likely was...or even Bradshaw. The idea is to put deserving players in the HOF and not water it down. I made a very simple statistical formula based on finishes as outlined above for every season in professional football history to date.
For those looking to vet it off-hand, the top-5 currently sits as: Sammy Baugh, Peyton Manning, Fran Tarkenton, Otto Graham, Johnny Unitas. Not bad.
All of the top 15 are in the HOF by my rudimentary metric except for Peyton, Brees, Brady, as they aren't eligible yet, obviously. The highest QB ranked that is not in the HOF is #16 - Ken Anderson. Which most people would agree is just about the best QB eligible for the Hall who is not in.
There are 28 QBs in the HOF. In my metric all of the 28 fall in the top-48 (which again, includes active players who will be in) - except one, Terry Bradshaw (71st). The rest of the bottom five of HOFers are John Elway (48), Jim Kelly (45), Bob Waterfield (43), Troy Aikman (42).
Eli Manning will almost certainly be adding zero points to his resume...he currently ranks: 108th. Harry Newman, Greg Landry and Matt Hasselbeck in the three spots ahead of him. Glenn Presnell, Matt Schaub and Bill Nelsen in the three spots behind him.
In other words, it would take an unbelievably disproportionate amount of weight to be placed on winning two games in non-consecutive seasons (as blessed as we are that those happened) to even remotely come close to even considering him a HOFer.
