Yes, the frontcourt was very good between Z and Boozer. Z only got in because of the positional need of the team and Boozer was still several years away from being an All-Star. But the rest of the team was trash by the time the season ended. Darius Miles and Ricky Davis were jettisoned in the middle of the season to prevent them from poisoning LeBron. In return, the Cavs got Eric Williams, Tony Battie and Jeff McInnis.
Maybe it's just me, but Miller, Leonard, Camby, Nene, Boykins, Birdman and Barry offered more help than what LeBron had.
