I'm of the opinion that the Bulls need to court Love if stuff with Melo falls through. I think they could offer Taj,Mirotic,some picks,snell,etc.
Question is how much are the Wolves gonna want? They're in a bad position because Love clearly wants out, but there are quite a few potential suitors such as the Warriors who can offer enticing packages. That competition might make it more difficult for the Bulls to offer an attractive package. The Wolves want promising young players, that's why I think adding guys like Mirotic and Taj(along with a few picks) may satisfy the Wolves.
In all honesty,though, if the Warriors can put together a deal the Warriors want(with/without Klay Thompson) and other teams like the Bulls fall out because they sign other players or something, I think Love ends up at Golden State. I suppose Houston is another possibility...they could offer guys like Terrence Jones and Chandler Parsons that the Wolves might be interested in.
Lance Stephenson is another interesting possibility. I think he could be a very good defender under Thib's system. He also rebounds very well and has decent passing ability(needs to work on staying in control), and can create his own offense. The issue is the contract of course, but if he's asking for 9 mil I would take him.
"But that doesn't really get the Bulls closer to a championship"
You don't know that, there's a lot of time left(and a lot of injuries and trades) before we get to April/May 2015. The Bulls could very well end up in contention with Noah-Taj/Mirotic-Butler-Stephenson-Rose(or whatever else they may add). But what if they make the 2nd round or something? What if they don't win a championship or even get to the conference finals? Should they have ever gotten someone like Stephenson in the first place?
What if next year comes around and Portland is looking at offers for Lamarcus Aldridge? What if they want Stephenson on their team because he played pretty well with the Bulls last season and he is young? What if he is the deal breaker?
I'm not saying that is WHY you get Stephenson, but getting Stephenson does not mean the Bulls are out of FA/NBA star talk in the near future. Obviously, you look at Melo and Love first, but I think the Bulls should look at Stephenson as well.
I really don't like adding either Marion or Gasol though. They're older and don't really fill needs. I guess it depends on the price, but I'd rather not spend for them.
