Postseason results: Lost to Simeon, 62-57, in the Class 4A Bloom Sectional semifinals

Why they're in the Power Rankings: Incredibly young last season, the Spartans were still a top-25 mainstay as plenty of that talent returns this season. Adams and Hurt will be one of the best backcourts in the area.
Did you know?: The most famous recent Marian Catholic alum, Tyler Ulis, has a brother entering the program this season as Ahron Ulis is a 5-foot-10 freshman.
2017-18 record: 25-9, 7-2 Public League Red-South/Central
Postseason results: Won Class 3A state title for second consecutive season.
Players to watch: Junior guard Adam Miller returns after a promising sophomore season. After a solid summer, Miller is viewed as a consensus top-75 national prospect in his class. Another junior guard, Marcus Watson, also returns after getting extended run last season as he's another major threat in the Morgan Park backcourt. And Lincoln Park point guard Chris Roberts transferred in to give the Mustangs another quality ball-handler and scorer.
Why they're in the power rankings: Coming off of back-to-back state titles for the second time this decade, Morgan Park will attempt its first three-peat this season. With a dynamic backcourt that includes big-name players like Miller, Watson and Roberts, this should be another season in which Morgan Park is a big favorite to make noise in Class 3A. Frontcourt stability and depth will be the key for Morgan Park's season as they have to find complementary pieces for the stars.
Did you know? Morgan Park has some of the most impressive postseason streaks in the state. The Mustangs have been a state qualifier in five of the last six seasons, a sectional champion in six straight seasons and a regional champion in eight straight seasons.
