While the Miami Dolphins are still in play and the Tennessee Titans could potentially be a dark horse in the Peyton Manning decision, it is believed by most that Manning will eventually choose between the Denver Broncos and the Arizona Cardinals.
In the latest of the SB Nation Channel video series on YouTube, they break down the reasons why Manning will end up pick the Cardinals to play in 2012.
The Cardinals have lots in their favor, but don't have the flexibility. The Broncos have a lot of cap room, so they can become the team that Manning wants. Arizona would have to be the team he already could step in and improve.
The Cardinals have the better talent, better place, a dome and a flexible coaching staff.
In Denver, he would be playing for an icon and replacing Tim Tebow, whom everyone loves there.
