In their 23 games this season, Marcus Domask was the high scorer 9 times, Lance Jones was high scorer 12 times, and earlier in the first few weeks of the season, Xavier Johnson and Dalton Banks were high scorers once each.
Leading rebounder is Marcus Domask with 6.0 rpg. JD Mulia averages 4.9 rpg, and no other player averages 4 rpg.
SIU has been outrebounded by opponents this season, and they currently rank 12th and last among MVC teams in total rebounds, and last in offensive rebounds-

Their average of 31.4 rebounds per game ranks 330th in Division I, and their average of 6.7 offensive rebounds per game ranks 352nd among 363 Division I teams.
SIU play a relatively small lineup-
Starters in their last 5 games have been- 6'6" Marcus Domask, 6'1" Lance Jones, 6'1" Xavier Johnson, 6'8" Clarence Rupert, and 6'3" Jawaun Newton.
Top reserves in minutes played are- 6'2" Trent Brown (17 mpg), 6'2" Dalton Banks (16 mpg), 6'8" JD Muila (16 mpg), and 6'7" Troy D'Amico (16 mpg, though he's played less lately).
So hopefully, Bradley's size and rebounding can help neutralize their offense and control the boards.
