Watched some highlights on YouTube... unfortunately they can shoot the three. #34 Cumberland is their stud......6’ 5” wing guard. They have a quick point who is the top 3 point percentage shooter in their league.
Looking at their season they held a lot of opponents to the 60's. Only losses were to teams I would say are considerably more athletic than Iowa. And as you pointed out Cumberland appears to be a player. Throw Moss and Dailey and their 10 fouls at this guy and harass the hell out of him. Give another PG the treatment teams give Bohannon and make the refs call 10 fouls while hand checking / grabbing the whole game. Do something different than let opposing guards carve the D up. Iowa cannot get into an up and down with this team. Work the clock, make them defend and grind out possessions getting post guys multiple touches.
