George played 46 minutes and scored 28 points after halftime Sunday, including making six of his franchise playoff-record-tying seven 3-pointers.
Roy Hibbert had 17 points and nine rebounds, continuing his recent surge after a poor-as-can-be start to the series. He helped Indiana overcome Washington's 32-2 advantage in bench scoring.
That was thanks mainly to 30-somethings Al Harrington, Drew Gooden and Andre Miller, who combined for 28 points, 13 rebounds and six assists. Wizards coach Randy Wittman likes to call that trio of not-yet-retired, best-days-behind-them guys - Miller, 38; Harrington, 34; Gooden, 32 - the ''AARP group,'' but they momentarily turned the game Washington's way with quite a second quarter and a key stretch of the fourth.
There even were chants of ''An-dre Mil-ler!'' when he made two free throws in the fourth quarter to make it 85-76. But George willed the Pacers back.
His 3 with 5 1/2 minutes left made it 85-79, and another 30 seconds later made it 85-82, giving him seven from beyond the arc, matching a mark held by Reggie Miller and Chuck Person.
John Wall (12 points, seven assists) gave Washington what turned out to be its last lead at 91-90 with about 2 minutes to go. George pushed Indiana back in front with two foul shots, and the Pacers then made a key defensive stand, forcing a shot-clock violation.
At the other end, Hibbert made a 12-foot turnaround hook shot with 1:02 remaining to put the Pacers up 94-91, the ball bouncing on the rim before dropping through. The 7-foot-2 All-Star center sprinted down the court, his arms spread apart and his smile as wide as can be.
Indiana's next possession ended with George Hill throwing the ball out of bounds for his team's 19th of 20 turnovers, but Harrington missed a shot at the other end. Yet another Pacers turnover gave the Wizards a second chance, and Bradley Beal was fouled. He made 1 of 2, and George - who else? - grabbed the rebound. Hill was fouled, and went 1 for 2 at the line.
So the Wizards trailed by three with 6.1 seconds left. They couldn't get the ball inbounds cleanly, though, thanks to more strong defense from the Pacers, and George corralled the ball.
The Pacers now head home knowing only eight teams in NBA history have ever blown a 3-1 lead in a playoff series.
They also know they're playing much more like the team that pushed the Miami Heat to seven games in last season's conference finals. Or the one that earned the No. 1 seeding by going 46-13 at the start of this season. And they're looking far less like the one that went 10-13 down the stretch this year, then needed seven games to eke past eighth-seeded Atlanta in the first round.
That is thanks in large part to George and, suddenly, Hibbert.
Washington was up by 17 at halftime, then pushed that to 19. The hosts were still ahead by 14 late in the third quarter before Hibbert dramatically became active, morphing from the Game 1 version (zero points, zero rebounds) to the Game 2 version (28 points, nine rebounds). He scored nine points and mixed in a block on Marcin Gortat during a 12-0 spurt that pulled Indiana to 70-68 on Hibbert's follow-up tip with 1 1/2 minutes left in the period.
The Wizards were ahead 72-71 entering the fourth quarter, but the Pacers tied it at 74 with 10 1/2 minutes left on George's three-point play.
A 9-0 run spurred by Harrington and Gooden made it 83-74 with a little more than 7 1/2 minutes to go, but Washington could not hold on., while George took over the game late.
