Seeing as the Chiefs are recognized as among the Godfathers of cheating in the NFL going back 50 years and the "cheater" in question has a Trophy named after him, I'd suspect there will be little who even remember this in 10 years.

The Patriots have won said trophy quite a few times actually!
The stupid people who don't know squat about the history of the NFL and actually think the Patriots cheated likely had bad memories anyway.
Heck - there might even be a "Belichick Trophy" awarded each season by then!
i have no idea what the reason for it might have been, but this was without a doubt the worst case study in crisis management in modern sports media (Mark McGwire's congressional Steroids testimony and its aftermath would probably be a distant second.) I read the terrific article to which you linked and didn't find a reference to what you said happened, which would help explain how bad it was.
Whatever the reason, the Pats just sat there day after day and week after week as lies became "truth." They had no organized system of credible surrogates hitting the web and ESPN every day telling their side of the story. There was no organized system of mass emails and blast faxes setting the record straight ten minutes after a lie was told on ESPN or elsewhere.
I know that the above wouldn't have completely "changed" the coverage, but the idiots who were making these stories up would have thought twice if they knew some respected voice was going to challenge their credibility ten minutes after they told another lie on national television. That's how crisis management works; you know that you're not going to get rid of the crisis, but you chip away at its foundations day after day.
As a result, the coverage became more and more emboldened and more and more one sided and more and more biased with each passing week, driven by a feeding frenzy of irrational, jealous fan bases in large media markets like New York, Miami, Philadelphia (which took its SB loss very badly) and Texas. Add in all of the smaller media markets like Indy and Buffalo and Jacksonville and St. Louis, where there is no love lost for the Pats, and it didn't take the suits at ESPN too long to figure out that there was ratings and clicks gold in this story.
The only organized effort of which I am aware to address the lies and bias was actually developed on this Board!!!
It's rule number one of crisis management in today's continuous media environment that you never let a bad story, let alone a blatantly inaccurate or intentionally misleading story, go unchallenged for more than a couple of hours. Instead, this stuff went on for weeks and months, took on a life of its own and, outside of New England and this Board, it became the "truth" that the Pats had used cheating to win their Super Bowls.
As for the rest of your point, i hope you're right and i'm wrong, but Spygate occurred in a 24/7 media environment unlike most of the wonderful examples in the piece to which you linked. i'm afraid that it is going to "stick" for a long time as a result.
and, i agree, i often thought that if BB won two more SB's, the trophy might one day be renamed for him. Noll has four rings, BB, Gibbs and Walsh all have three; Shula made six trips to the SB and Landry five, both winning two of them. So, five rings would put Belichick in a class by himself.
