I agree that 2 of the potential starters seem a given- Brown and Childs.
And, Kennell, who only started 11 of 35 games last season seems likely to me to start this season with van Bree, Lundy and DLO gone (as well as Pittman, Hodgson), but not a certainty.
And IMO, the other 2 starting spots are more up for grabs, though I think Danya Kingsby might be a starter, since he gives Coach Wardle more athleticism and defensive ability at the guard position.
Koch Bar will get plenty of playing time, but I don't think he is a guaranteed starter. Recall that Bar, who started the first 18 games last season, did not start the final 17 games. Then after Bradley started the MVC season 0-5, Bradley Head Coach Wardle went with the smaller, more mobile, better shooting lineup with Luuk van Bree at the "5". With Koch Bar coming off the bench, the team went on to finish the regular season 9-4, with all 4 losses coming to the 4 teams who finished ahead of Bradley. Then the Braves went 3-0 in the MVC Tournament and played in the NCAA with the smaller lineup.
So maybe the 5th starting spot is Bar, but could also be Henry, Gabriel, or Boya,
