Daughty will be the biggest rock star the show has ever had. He has a great voice for both live performances and for CDs. He also seems very well-grounded.
I agree, and would add Daughtry is the best by far to ever appear on the show. I also think that Mandisa was better than either of the two left.
He was also one dimensional and was never able to broaden his base, which is why he got voted off.
