Rector poured in a game-high 26 points, giving the Couch Indians fits down low all evening long, as the Bulldogs pushed past Couch 57-43 to claim top honors in the conference tournament.
Only three other players besides Rector scored in the game for second-seeded Van Buren and two of those, Michael Duncan (15 points) and Daniel Newberry (14 points) notched double-figures.
But then Couch's big force inside, Derrick Martin, came alive to keep things from getting completely out of hand for the Indians.
Martin went on a personal 9-zip run to pull Couch within eight, down 35-27. Martin logged a team-high 18 points, 16 coming in the second half, for Couch.
However, that would be as close as the Indians could get to Van Buren.
The Bulldogs opened the final frame with four straight technical foul free throws from Rector to open up a 42-29 advantage.
The fourth period saw plenty of shots taken from the charity stripe by both teams, with Van Buren easing to a 57-43 win.
Eddie Meier gave Couch its only lead of the night with a jumper to start the contest.
Rector responded with seven points in the first period to give Van Buren a 12-6 lead after one.
Chris Taylor (11 points) slid inside the paint for the Indians' first bucket of the second and Jesse Janes (eight points) hit a spinning shot in the lane, but the Bulldogs clipped off a 10-2 burst to pull ahead 22-10 with 3:32 left until halftime.
Couch fought back with a bucket by Janes and two more from Taylor, but Duncan hit a trey and Rector knocked down a shot on the low blocks to send the squads to intermission with Van Buren on top 27-18.
Derek Orchard and Brandin Orchard finished with two points apiece for Couch.
