Bulls earn a 'B' in one publication's offseason grades

The Bulls were a pretty good team last season, and are betting that the exact same group, along with the addition of rookie Bobby Portis and a new head coach in Fred Hoiberg, can be even better this year.

There were no splashy external free agent signings, and no shiny new roster additions. 

But the small tweaks that were made were enough for the folks at Sports Illustrated to give the team a B grade for the work it did during the offseason.
