It helps that he actually got to play the game on "Celebrity Jeopardy." But truth be told, it's because he's watched the show for most of his life. Because of that... he learned from the best of the best in the host world: Alex Trebek.
"The beauty in what Alex did was he could get so much accomplished by using very few words. I tried to model many of the things he did; but the most important thing was just to bring the respect that I had for Alex and for the show," said Rodgers.
The premiere athlete is known as a fierce competitor on the field. And he prepared for this new job with the same intensity.

"It was an audition to be the full time host that's how I approached it, that's why I spent hours practicing and preparing, because I wanted to step in and 'Wow' them," said Rodgers. "It was like 'no I got it, I watch the show.' I'm not an expert of it but got the basic beat points and ready to rock and roll."
Rodgers said he didn't come across any football super-fans on the "Jeopardy!" set.
"A lot of contestants were more regionally based, so there wasn't anybody from Wisconsin who was freaking out, I think many people didn't know who I was which was beautiful in its own. It just reinforced the fact that these are highly intelligent people who spend time reading books not watching TV," said Rodgers.
For hosting, "Jeopardy!" will be making a donation on Aaron's behalf to the North Valley Community Foundation. It's helping re-build communities in Northern California that have recently suffered wildfire disasters.
