I was in New Orleans for the Giants-Saints game in 2009, when both teams were undefeated, and I went to the game with a lifelong New Orleans resident and Saints fan. I was dressed in full Giants regalia all weekend.
We got pasted (and the Saints went on to win the Super Bowl that season), but I have never been treated so well as the fan of an opposing team in my life. The Manning family is basically royalty there.
I don’t think I bought a drink all weekend, and I met several people who grew up with Eli, dated him, played sports with him at a young age, etc. To a person, they all raved about him and said he was a great kid with a great personality. As it was described to me, Cooper and Peyton were always with Archie and always 100% sports, but as the youngest, Eli spent a lot of time with his mother and was more laid back and easy going, but he also obviously learned a lot by watching his brothers.
I think you can see a lot of that in his personality.
