He ought to know. You don't last as long as him in the business and not know such things. I think he's on the money.
I do, too. I don't think there's a real star among this year's group, but think that Syesha has developed and improved the most over the course of the season. As a result, I think she has the most long-term potential.
I think Cook is probably the most saleable in pop music, and I think Monchichi appeals to the same tweens and young teens who like Disney's Hannah Montana, the Princess Diaries, etc. I think Brooke is too emotionally overwrought to withstand the rigors of a career in show biz. And I think Dreads has a cute face, a seemingly nice personality, but not much musical talent -- at least none we've seen on the show.
