Don't think you can compare the stats directly given that teams on average are hoisting 45+% more 3-point FGs. That appears to affect shooting, rebounding, and turnover percentages probably due to the spacing of teams' defenses in the era of 3-ball. Instead, looking at how both teams ranked may be the best indicator of how they stack up given the way the game was played in both eras.

Pacers were below average shooters, ball-handlers, and creators of turnovers. Cs are average in all those categories. Pacers were elite rebounders compared to the Cs who are above average. Both teams were elite defenders against opponent's shooters. Would give the edge to the Cs overall, especially because of the shooting, without arguing about player A vs player B.
