Dean Oliver suggests that four factors (rebounding, turnovers, shooting percentage, free throws) capture a basketball game.
The Bulls' offense last year (ORating: 107.5, Rank: 11) was predicated on Oliver's last factor, free throws. The Bulls were middle of the pack in shooting, but made up for it by consistently winning the free throw battle. Thibodeau drilled his team to get into the bonus early in quarters, while avoiding fouls on defense to prevent opponents from reaching the charity stripe.
Based on Hoiberg's tenure at Iowa State, it's unlikely he will continue using this area of Bulls' strength in his uptempo offense.
