With the win, the Heat are halfway to what would be an upset: a No. 8 seed over a No. 1 seed, something that has happened just five times since the NBA moved to the 16-team playoff format in 1984.

Those who did: Denver beat Seattle 3-2 in 1994, New York beat Miami 3-2 in 1999, Golden State beat Dallas 4-2 in 2007, Memphis beat San Antonio 4-2 in 2011 and Philadelphia beat Chicago 4-2 in 2012.

Butler was hurt midway through the third quarter after taking a shot near the rim and falling on his back. He stayed in the game briefly, departed for a brief locker room stint, and returned with a large bandage on his back, with the Heat saying he would be back.

He didn’t, because he didn’t have to. The game was set, and Miami eventually led by as many as 29.

Still, it was a grim end for Miami, first with Butler banged up and then with Victor Oladipo, who has spent years dealing with injury problems, leaving late in the fourth quarter after apparently hurting his left knee. Oladipo was expected to play a bigger role for Miami in the postseason after Tyler Herro’s injury.

The first half couldn’t have gone better for Miami. Butler scored 17 points in the first quarter, the Heat went 19-0 at one point, set a franchise record by hitting 12 3-pointers in the half, and still only went 66-53 at halftime.

The reason, again: Milwaukee was making 3-pointers, again. The Bucks made 25 of them in their easy Game 2 win and went 10-for-18 from deep in the first half on Saturday.

But the Bucks cooled off after halftime, shooting just 5-for-21 from 3-point range, and the result was never in doubt.
