Most of the players on our current defense would not make the cut for Jimmy in 92 and 93. Lee and Lawrence, but not much else.
The special teams we had back then was several tiers above what we have now besides kicker and long snapper.
Offenses are somewhat similar except that Dak has a long way to go before being on Aikman's level. The 92 and 93 WR core was light years better. Witten is better than Novacek was, though Novacek was certainly no slouch. The lines are comparable for sure, but we had more depth back in the day because it was pre free agency. Zeke could potentially be a 12000+ yard career back. Emmitt is the greatest ever, but Zeke is close enough.
Conclusion: the 92 or 93 Cowboys destroy the current team 45-17. The defense would have little trouble shutting down the passing game, and Zeke would be the greatest worry. The Aikman-Emmitt-Irvin offense would annihilate this current defense.
