Trevor Mbakwe dunked with ferocity. Ralph Sampson III pounded on his chest after drawing a foul on a putback. Colton Iverson crashed into the lane and any defender in his path.
The 16th-ranked Gophers used bulk to beat Northwestern 81-70 Wednesday night at Williams Arena.
With Al Nolen sidelined indefinitely by a broken foot, Tubby Smith went big and started Mbakwe, Iverson and Sampson III next to Blake Hoffarber and Rodney Williams.
The lineup change resulted in the most productive outing of the year for Gophers post players.
Mbakwe recorded his 12th double-double of the season with 18 points (tying his career-high) and 14 rebounds.
Iverson scored all 15 of his points in the second half. The 6-11, 260-pound center hadn't topped double-digit scoring since a Dec. 23 victory over South Dakota State. And Sampson added 14 points.
"The big lineup was pretty impressive tonight," Smith said.
Blake Hoffarber filled in for Nolen at point guard. He scored a game-high 20 points with four assists and four turnovers for the Gophers (16-4, 5-3 Big Ten).
