Del Negro is terrible, and this is a team that was very poorly put together. They have a (potentially) great PG, an excellent roleplayer at SF, a good role player at Center, and then a bunch of bench guys who are paid like starters.
Last year they let their best "finisher" walk, and failed to replace him (I am a huge Deng fan, but he brings completely different things to the table than Gordon), and they haven't addressed their need for a legit big man for years now.
This is a team with a ton of tradable assets (Miller's expiring contract, Hinrich, Thomas), and two glaring holes in the starting lineup. I really hope they decide to make some dramatic moves soon to push this team back into the playoffs instead of just holding out to hope they can convince Wade to join them in the offseason. Rose is too good a player to not have him showcased in the playoffs.
