Its not so much Rose as it is the 2nd option.
I have a hard time believing Deng replicates the year he just had, Boozer isn't as bad as people are making him to be but he's not that great either, Noah isn't a reliable scorer against above average competition, Korver/Brewer/Bogans/WhateveratSG has been unreliable all season.
I think Gibson will be the type of player the Bulls are looking for, but it will be for another team.
