In his defense, he is right about shEli not being HOF-worthy.
The announcers touched on the factors that will get Eli into the HOF: 2 SB wins, top 10 all time in passing yards and passing TDs. Left unsaid, but maybe more important than those is that his last name is Manning and he played in New York. Something else that they mentioned that I hadn't realized is that Eli's career record is 113-110. With 7 games to go this season, his career record by the end of the season will still be hovering around .500.
If you look at the other QBs who are also in the top 10 in yards and TDs, almost everyone else is well above .500. That includes his contemporaries, like Rivers and Roethlisberger, as well as Elway, Brady, Marino, Favre, Peyton, Brees, Rodgers, etc. The only players in the top 10 with those stats who are close to .500 are Tarkenton (124-109-6) and Warren Moon (102-101.) Barring an injury, Moon is going to be knocked out the top 10 in passing yards by the end of next year by Matt Ryan. That will mean all those QBs not only put up great numbers, but their teams also won a lot, except for Eli.
The announcers also discussed Eli's lack of playoff success outside of the SB years. In a 15 year career, his team has made the playoffs 6 times and only won a playoff on 2 of those occasions. You can't diminish that those 2 time resulted in 2 championships, but there's no other great playoff performance to point to, like a run to the NFCCG one year. Brady gets held to a ridiculous standard, like he didn't win a SB for 10 years or losing a SB is worse than not making the playoffs. Meanwhile, Eli has missed the playoffs in 6 of the last 7 seasons (counting this year) and has zero playoffs wins over that span.
Manning will get in the HOF for the reasons I mentioned in the first paragraph. He definitely doesn't deserve to be considered among the all time great QBs, though.
