And now some input from someone who knows what they're talking about: https://www.theringer.com/nba/2018/7/16/17575004/jabari-parker-chicago-bulls
Some may assume Parker’s presence will take the ball away from Markkanen, thus hindering his own progress. But I’d bet that Parker will have a positive effect. There’s a perception that Parker needs the ball, but he can be used in a multitude of ways on the floor, just like Markkanen.

Hoiberg ran offense through Markkanen in the ways you’d expect: in pick-and-pops, post-ups, and spot-up situations and by running him through screens. But Hoiberg also used the 7-foot Markkanen as a pick-and-roll ball handler.Now the Finnish big man has a frontcourt partner who can also handle or screen and pop for 3s or rumble down the lane.

Considering how frequently defenses freely switch screens on high pick-and-rolls, their interchangeability could lead to preferable mismatches for the Bulls’ offense with either player in space against a slower or smaller opponent.
Parker also shouldn’t negatively impact Carter on offense. In the half court, Parker can serve as another target for the rookie’s playmaking skills. Hoiberg could run Carter through a ton of high screens and feed him on the short roll, where he’s skilled and savvy enough to score, pull up, or make a pass. Parker likes to cut, and it’s easy to envision him playing well off of Carter.
Parker, Markkanen, and Carter can also all rip down rebounds then take the ball up the floor and score in transition or initiate the offense. It’s a very modern team.
