Which NBA Team Has Improved the Most This Offseason?

Many teams this season have made some important transactions in the free agent market. Obviously, the Heat have improved a lot with LeBron James and Chris Bosh joining, so I won't include them in this list. Teams I will look at will be the Bulls, Lakers, Jazz, and the Celtics.

1. Chicago Bulls
The Bulls have almost become the Utah Jazz East, signing three former Utah players (F Carlos Boozer, G/F Kyle Korver, and G Ronnie Brewer). These three players, along with G CJ Watson, and F Kurt Thomas, have greatly improved the Bulls team. Also, they fired coach Vinny Del Negro, and hired Tom Thibodeau. They did lose Brad Miller and Kirk Hinrich, but Boozer can fill the hole in the post nicely for Chicago, and Watson, Brewer, and Korver can fill in there. Derrick Rose is a very good young PG, and Joakim Noah is a solid rebounder and post player. The Bulls will definitely be playoff contenders next season.

2. Los Angeles Lakers
Yes, the defending champs have improved. They not only kept coach Phil Jackson and PG Derek Fisher, but they also signed G Steve Blake, F/C Theo Ratliff, and F Matt Barnes. Barnes is the key signing for the Lakers, giving them a top defensive perimeter player off the bench. Ratliff is also a good shot blocker and a decent back-up in case injury strikes Andrew Bynum again. They lost Jordan Farmar (to the Nets) and Josh Powell (to the Hawks), but Steve Blake can run the point with the 2nd unit for the Lakers, and Ratliff can replace Powell.

3. Utah Jazz
The Jazz did lose several players (Boozer, Brewer, and Korver as mentioned before, as well as G Wesley Matthews), but the sign and trade deal with Minnesota that landed them Al Jefferson was huge. Jefferson will be a great fit in the Jazz offense, and Raja Bell is a great defender, and has a history of matching up against Kobe Bryant.

4. Boston Celtics
The Celtics had a great offseason in terms of keeping their team together. There were rumors that Ray Allen might leave, or that Paul Pierce would go elsewhere, but the Celtics were able to retain these two, as well as G Nate Robinson and G Marquis Daniels. Coach Doc Rivers also has agreed to return to the team. F Rasheed Wallace retired, and F Tony Allen signed with Memphis and F Shelden Williams signed with Denver, but these three losses shouldn't hurt the Celtics that much. F Jermaine O'Neal was the Celtics only major free agent signing, but he can replace Wallace (and Williams, who didn't contribute much to the team), but Allen could be missed as a spark off the bench.

Overall, I think the Bulls made the most improvements, followed by the Lakers, the Jazz, and the Celtics.
