Why we underestimated him: Lil Wayne was the main reason his group—Playaz Circle—scored a hit with "Duffle Bag Boy." Also, his name was Tity Boi. Nuff said. 

When he proved us wrong: When he changed his name to 2 Chainz, released his stellar mixtape, T.R.U. REALigion, and created a whole new identity for himself.

2 Chainz did such a good job of rebranding himself in 2012 that some casual rap fans didn't even realize that 2 Chainz was Tity Boi. T.R.U. REALigion was full of fun rhymes and lots of personality (even the mixtape's cover, which featured 2 Chainz using a urinal, got a laugh out of us). And thanks to the new moniker that he created, 2 Chainz' debut solo album, Based on a T.R.U. Story, debuted at No. 1 on the Billboard 200 chart. To say 2 Chainz has made a huge transformation as a rapper would be an undastatement.
