Zach LaVine post All-Star numbers:
29.1 ppg, 4.5 apg, 3.6 RPG, 54% FG, 46% 3pt
The Bulls aren't going to blow this up, but they should retool and I'd do it around Zach. See if you can get younger and better fits - Derozan in a 3 way and than I have no earthly idea what you can do with Vuc in a S&T to free up other options. Maybe Vuc stays, I don't know. I do know you need to surround Zach with a good PG and solid defenders.
If the Bulls could just maintain and get a good PG - than awesome, we know at that point this is at least an above average team - problem is Derozan and Vuc are also on the wrong side of 30, so I don't like over-leveraging into a team that has more long term downside than upside (and the upside is pretty limited anyway - even as i describe above - they stay status quo and land a good PG, I don't think they are a title contender - but they are probably a pretty good team).
