They got what they got. You don't get points for "shoulda"...it's all conjecture. The 1990s Cowboys ONLY got 3 and thus should not be considered on par with any team with 4+ Super Bowls.....hell, Pittsburgh "shoulda" had a 5th during the 1970s (the 1976 Steelers were maybe the best D they ever had, but had a couple HUGE injuries in the playoffs and basically played the AFC Championship game against Oakland with ZERO running backs). Thems the breaks, injuries, coaching changes, bad weather, bad calls, etc......Oakland lifted the trophy and that was that.
