The play came in the final minute of the third quarter on Wednesday at Target Center in Minneapolis. Minnesota led 99-91 at the time when Exum received a pass down the right flank and took off toward the Timberwolves' half of the court. He dribbled by several defenders before crossing the 3-point line.
He coasted into the paint before going up and pulling the ball back far in his right hand. He brought it forward for what looked like it was going to be a highlight reel finish, but Tolliver had other plans.
The 6-foot-6, 190-pound Jazz guard met the 6-foot-8, 250-pound Timberwolves forward in midair. Tolliver used his frame to shield off Exum before using his right hand to stuff the dunk attempt. Exum crashed to the floor hard, but his teammate Donovan Mitchell followed the shot for an easy lay-up.
Exum finished the game with 14 points, four rebounds and three assists off of the bench. Tolliver had three points, three rebounds and two blocks for the Timberwolves.
Derrick Rose led all scorers with a career-high 50 points in the victory.
The Timberwolves face the Golden State Warriors at 10:30 p.m. on Friday at Oracle Arena in Oakland.
