"You want to take those shots," Dunleavy said. "You want to take them and make them. At that point I think it was eight points and only less than a minute left. Not enough possessions in the game for them to come back unless we completely fall apart."
Milwaukee took a 12-point lead on a 3 by Dunleavy with 6:44 left in the first half, but Brown scored nine points to spark a 15-5 run as the Suns tied it at 48 on their way to a 56-53 lead.
Phoenix continued to roll at the start of the second half, scoring the first seven points to extend their scoring run to 13-0 over a span of 4 minutes across the second and third periods, and led 63-53 on P.J. Tucker's 3-pointer with 8:27 left in the third.
Another 3 by Dunleavy tied it at 80 with 8:25 to play.
"You have to be able to make plays down the stretch to win games, especially close games," Suns coach Alvin Gentry said. "They made them and we didn't. We got the ball right at the basket and we couldn't get it in."
The Suns' troubles in the fourth quarter largely were self-inflicted.
Phoenix committed six of its 18 turnovers in the fourth, leading to nine of Milwaukee's 28 points in the final period. The Suns shot 29.2 percent in the quarter (7 of 24) and 31.9 percent for the second half.
"It's tough," Goran Dragic said. "It's different players than in the past for the Suns. In the past, four players spread the floor and one big guy rolls or plays the low post and, creating from there, you have more spacing. With this team we don't have this.
"In the past, we were a running team. We ran a lot and scored some easy layups. We don't do that anymore."
