Yeah, that's what I meant. Sign him as a FA.
We aren't going to have the cap space to make a run at a Carmelo, even if we amnesty Boozer. We'd also have to ditch Taj and MDJ.
So in the absence of that, use your two first round picks on young wing shooters and rebuild your front court. Noah-Taj-Mirotic-Gasol perfectly compliment each other (much more than Noah-Taj-Boozer-Muhammed), it opens up the lane with both Gasol and Mirotic capable of stepping out a little bit, and you've got rookie shooters clearing the lane for Rose even more when he gets back.
You've also got your lockdown wing defender of the future in Butler. Say your draft picks are say, James Young and Rodney Hood (see
http://www.draftexpress.com/nba-mock-draft/2014/ -- wouldn't be too far off). Those are both capable shooters as well.
That gives the Bulls a dominant front court, wing shooters to space the floor, great defense both up front and in the back court, and Rose returning.
If Rose is back to form, that team can compete for a championship in the next couple years.
