Memphis may have been a bottom 10 team in half court offense. Midrange game is where DeRozan is best at. Also my belief he could be the right mind of vet to bring some discipline and maturity to this young-ish team.
Bulls ranked 5th defensively on the year and add two more defenders. These two additions along with the likes of Caruso, Pat, & Lonzo means they might struggle scoring and/or shooting but defense will not be a problem.
