If Eli Manning's career ended today, he would most likely not make the Hall of Fame. He's 7-1 on road/neutral playoff games, he's 2-0 in the Super Bowl, he's a two-time Super Bowl MVP and a has made the Pro Bowl (2008, 2011) twice. His brother Peyton is 1-1 in Super Bowls but made the Pro Bowl 11 times out of 14 years which makes him a first-ballot Hall of Famer.
However, if Eli Manning never wins another Super Bowl or goes to another Super Bowl, but passes for over 3,000 yards with at least 25 touchdowns each year for at least another 4 years, he will eventually join his big brother in Canton. His numbers by then will suffice. And remember, he has never missed a game since being drafted by the New York Giants. In my opinion, he is BETTER than Peyton because he is better when it counts!!!
