Ivaroni is an excellent big man coach, KT is one of the best fundamental big men in the NBA, amare still doesnt box out after 5 years around these guys. Mojo, its like I said, if the suns want to go defensive, they must unload DA AND some players. Flip Saunders is not known to be a defensive coach, but his players are known to be defensive players.
Prince, Wallace, Hamilton, Billups are defensive minded players and always have been. Amare stoudemire has shown very little progress in boxing out and position defense in 5 years. I know Ivaroni, he was a defensive specialist on the early 80's 76ers when I used to live in the phila area. If Ivaroni cant teach amare to be a defensive big man, no one can. LB has shown some progress, but its very slow, not worth the trouble to train him to be an average defender, marcus banks would have been a better choice for that. DJ has all the tools, if you want to go defensive trade barbs, amare, nash, get rid of DA, hire van gundy and get players with value in return. It didnt do much for the rockets though, they cant beat the spurs either with all their defense. I dont have a problem with reworking the team, but the "just trade DA" guys are way off, as the players must fit the system.
