The Cavaliers

The Cavaliers are one of the biggest surprises of the 2011-12 NBA season, currently sitting at 7-11 overall. They are tied for ninth in the Eastern Conference right now, and if the young team continues to gel, there's a possibility that the Cavs could sneak into the eighth spot by the end of the season.
The one thing that the Cavaliers lack, though, is a presence of veteran leadership, aside from Antwan Jamison, and that's something that signing Allen Iverson for the $1.4 million veteran minimum could bring to the team.
Sure, Iverson isn't known for his skills as a leader, but the production that he could bring off the bench at both the point guard and shooting guard positions could add a much needed spark off an otherwise underwhelming Cavaliers bench.
Iverson is ready to fit into whatever role a team needs of him, instead of trying to be a star player like he once was. And if he is able to do that, he could help the Cavaliers turn the corner in the Eastern Conference.
Adding Iverson for the Cavaliers would also increase fan interest, which has been seriously lacking ever since "King James" took his talents to South Beach
