And it shows in the putrid product, these chiefs teams who won back-back would lose by double digits to the last franchise to do it- the 03-04 pats teams. The quality of play, skill and execution is almost as bad as the fake and gay commercials
Not sure what you're basing that on, because demographically the most recent Super Bowl was much better to watch from a CF perspective, such as McCaffrey, Kittle, Purdy, Juszcyzk, Kelce, Watson, three excellent d-players on KC, Bosa on SF, etc.
In the Super Bowl following the '03 season, both the Patriots and Panthers started seven Whites, but for both teams four of those starters were on the o-line. Neither team had a White receiver and Carolina's TE was the forgettable Kris Mangum. Dan Morgan was the MLB for Carolina, and Mike Vrabel and Tedi Bruschi were on D for New England (and Bruschi had a Mexican parent and looked it but most here treated him as an honorary White and rooted for him.) Other than Tom Brady and Jake Delhomme (who wasn't a particularly good QB), there was precious little to cheer for. The Patriots teams we remember fondly now because of their White dominance on offense didn't come along until later in the '00s.
As for quality of play, it hasn't declined much over the past 20 years. The NFL discarded a number of previous fundamentals a long time ago and suffers from a number of deficiencies that can be attributed to placating the needs of the Caste System, but I don't think the teams were noticeably better 20 years ago than now, overall pretty much the same old same old ever since the Caste System went hard core in the mid-1980s. My guess is that both the 49ers and Chiefs would beat that Panthers team, while the Patriots would be more of a toss-up.
But the commercials have certainly gotten immeasurably worse, and they were hard to take then.
