Dileo needs to head back to the front office. This team needs a better coach. We need a couple of guards and another big man in order to compete. Brand would have helped, IMO but not enough.
I'm not blaming DiLeo. He got this team to play 5 games over .500 during the season with next to no talent. He has a PG who's not even good enough defensively to stop JJ Redick. His guards not named Andre are Willie Green, Royal Ivey, Lou Williams, and Kareem Rush. He has no players on his bench between 6'5 and 6'9 to guard SG/SFs when Iggy or Thad need a break. His big men are Sammy D, Reggie Evans, Theo Ratliff, Donyell Marshall, and Mo Speights. He's not the one who came out totally flat tonight, and blaming a coach for a team coming out flat is just scapegoating.
Now, I'm not saying that DiLeo has been good, but be careful what you wish for. He's been passable as a coach, which is better than most in the NBA.
