Simpson used its size and versatility in the post to counteract the speed of Pickering on the Thursday night of the Vernon Parish Tournament.
The Broncos jumped out to a lead near the end of the fourth quarter and never surrendered it, defeating the Red Devils 58-49 at Hornbeck High School.
Simpson (7-10) had three post players score a combined 44 points to take advantage of the smaller Pickering team.
"At a small school, you have what you have, and we were blessed with size," Simpson coach Stephen Briscoe said. "Our problem all year has been getting the ball into them and we did a good job at times tonight doing that. In the second half, we didn't do it as well. We had some silly turnovers, almost as if we already had the game won."
Pickering (7-7) and Simpson were tied at 8 midway through the first quarter, but the Broncos finished the quarter on a 10-2 run.
"We can do better. Our second leading scorer wasn't there and we didn't stop them down low," Pickering coach Robert Carter said. "They're bigger than us so we just let them get layups."
"It was a problem last year and last year. We just don't play well against teams with size."
Simpson extended the lead to 37-24 at half, but the Red Devils quickly got the deficit back down to single digits with a pair of free throws from Ty Jackson.
"They have some really aggressive girls and good athletes on the perimeter," Briscoe said. "If you're not careful about meeting the pass, they they'll jump in front of it."
In the fourth quarter leading 47-37, Simpson sealed the win by getting to the rim with five layups
Payton Miller led all scorers with 23 points, and Ally Berry added 11 points for the Broncos.
"They helped get the pressure off of us because they can handle the ball and see over the press," Briscoe said. "They've done a good job of helping us with our point guard in foul trouble. Sarah Flatt (10 points) did a great job attacking."
Mahogany Griffin led Pickering with 21 points, while Payton Parker added 17 points.
"(Griffin) had a good game," Carter said. "She's a senior that plays hard all the time. She does it all. If I had five that worked as hard as her, we'd be alright."
