In this era he'd probably average 25-28ppg, 14-17rpg, 3bpg and 3apg, easily MVP caliber numbers. I can't see any center breaking the 30ppg threshold in this era with the zone and guards that can't throw entry passes.
However, nobody is tossing around a prime Shaq, in the Wilt vs Shaq debate I think it's overlooked that Shaq's post game and footwork was actually more polished than Wilts. Shaq's game with his back to the basket is really underrated, he's just viewed as some lumbering oaf when the nikka was actually really skilled and had moves/counters for days.
