I may not have been clear, but I'm explicitly stating the roster as a whole needs a variety of traits.  They can't all come from one position unless you have a LeBron, but even then, you need enough traits from the other guys.
You need enough guys whom can get a shot off when the offense breaks down.  This is the one area Zach really brings to the table that we don't have a whole lot of.  You need someone who can just get points in isolation when scheme didn't yield you anything.  That's really what the Bulls need to replace if Zach leaves IMO.
You could make an argument that Sato/Thad are more valuable than Zach?  Wow. Didn't expect that coming from you. 
Last year Sato/Thad weren't, but if you go back to how they were in Washington/Indy, where they were competent two way players, then they won't replace what Zach did, but they might help the team more if you find another way to replace what Zach did.
Maybe Coby can do it as well as Zach?  Yeah.  Maybe Carter can also.  And Hutch.
Coby definitely can create shots in isolation.  Not as well as Zach yet, but he can definitely do it.   Obviously Carter/Hutch don't won't do that, and I know you were just being facetious.  If you moved on from Zach and had more two way players, part of the thought is you won't need to create so many shots in isolation, because a more functional offense will spread the ball around more and create less hero ball scenarios.  Your defense will be improved and also allow for less scoring.
We won't have a dominant 25 PPG scorer if Zach leaves necessarily, and no one needs to necessarily become that guy.  You can make the case that packing the roster with a well rounded equal opportunity offense where everyone can defend will get you more wins for the same money.
Please make that argument.  I have to hear it before I let this color my perception of every other post you have ever made.   

Man that's a lot of pressure 

I like LaVine, I think he's a good player, but he hasn't made the Bulls a great offensive team.  You see the stretches where he goes into hero mode and the Bulls offense tanks, he isn't a guy who can carry an offense.  If you agree with me so far there, then it isn't a stretch to say that his biggest strength, which is shot creation for himself, is somewhat offset by his weaknesses.  He's just not quite good enough to lead a team, and his overall skillset loses value in a secondary role.
The Bulls will need to find more iso creation if Zach leaves, but they will likely be able to improve in other areas if he leaves too.  Granted, maybe Zach will also improve in these other areas under Donovan and maybe he will become a no brainer max guy.  It is a possibility, but I think he's been in the league too long for me to think there is a lot of improvement left there.
