I hear you on where my new is in terms of his level of play, but think about the attitude change this team would have if you swapped out Manu, Bonner, and Gary Neal for Dwight Howard. Three pros who don't complain, two of whom are straight up assassins with ice water in their veins, for a known chucklehead.
Not saying I wouldn't take Howard. He is an elite talent and you need talent to beat talent. But you have to keep in mind what makes this franchise run, and that is guys who are over themselves. Not true of Howard by any stretch.
