Given that the Bulls and Celtics exchanged various proposals centered around Butler last June that featured three to four assets as the price, it's logical to assume the Bulls would need at least two more assets on top of the Nets' first-round pick even to begin the internal debate process. Jae Crowder, Marcus Smart and Avery Bradley were players involved in last June's talks, the Tribune reported at the time, along with the No. 3 overall pick and possibly another first-round selection.
