The two squads met back in late November at the Zachary tournament with Scotlandville, which has only lost once all year, getting a 65-60 win.
"They're taller than us," the 6-foot-4 Sims said. "They have (6-6 three-star forward) Brian Bridgewater and also a 6-9 and a 6-8 guy.
"We're fast and all of our guys can shoot good. We're playing at ULM and should have a nice crowd. We have to rebound, make our shots and make free throws."
The tallest player on Ouachita's squad, Sims possesses the athletic ability to jump out of the gym.
He holds a large number of gridiron offers and says Alabama continues to maintain the lead to land his services.
He plans to commit to the Crimson Tide during summer camp, although a couple programs hope to persuade Sims to change his mind.
"I talked to the new wide receivers coach at Alabama," Sims said. "He seems like a cool dude. Coach Saban has spoken real highly of me."
What does Sims think about his higher ranking?
"I told my mom and she was real happy," he said. "I have to keep balling out, though."
