Not really. Their schedule has been cake so undefeated is an overly simplistic way of evaluating their strength and when you play their kind of defense you slow the game down, reduce possessions and thus reduce your own scoring chances. They've also let off the gas multiple times in the 4th qtr due to comfortable leads. Pacers have 3 starters who are averaging 30 mins or less per game. An interesting note I saw the other day, Paul George is 2nd in isolation scoring this season, behind only Durant.
