Apples and oranges. Different era.
Pretty much. I agree with the basic idea, insofar as no Patriots team could monopolize talent in the salary cap & free agency era like the old Cowboys (and 49ers and Steelers...) teams could. But you start looking deeper and things get weird.
The average player is bigger and stronger now than they were in the early 1990s. It's not a huge difference but it's there. The Cowboys had the cream of the crop from that era, but you can still end up with mismatches that go against them like a 269lb Cowboys center trying to block 350lbs of Vince Wilfork for instance. It's also fair to ask who the hell covers Rob Gronkowski, their strong safety in 1992 was Thomas Everett, who was 5'9". Darren Woodson would be a fun matchup there, but he didn't come into his own as a player until Jimmy Johnson was gone, at which point you've got a
Switzer vs. Belichick coaching matchup which is the biggest lol imaginable.
Another wrinkle is the Patriots would be running offensive play concepts that nobody on the Cowboys had ever seen. Probably some coverages they wouldn't recognize immediately, too. The Patriots are used to rules favoring the pass, but what does prime Revis look like
if he's allowed to mug the hell out of receivers too? It's hard to root against Irvin (duh) but it's food for thought. A lot of this stuff cuts both ways to some degree.
