If forward Luol Deng and the Bulls are talking contract extension, as one rumor indicated, that would be news to both sides. Deng’s camp maintains that all has been quiet on that front, and the Bulls have been knee-deep in draft scouting reports, making an occasional call to see if there are any takers for shooting guard Richard Hamilton. But as one NBA scout indicated during the Finals last week, any of the teams that are serious about dethroning the Heat in the Eastern Conference next season should sit tight until the first domino falls in Miami. Game 6 hero Ray Allen can opt out of his contract, and there’s still speculation that the Heat could break up its “Big Three’’ by trading Chris Bosh. Also, the 2014 free-agent class could be headlined by four-time MVP LeBron James. If he decides to leave Miami, James will be looking for a team that can afford him and has championship capabilities. The Bulls, with Derrick Rose, Joakim Noah and Jimmy Butler, would fit that description. But giving Deng an extension would take the Bulls out of that argument. As the Bulls learned in the summer of James’ move from the Cavaliers, consolation prizes such as Carlos Boozer aren’t bad, but they’re not James.
