Listen to Bill Belichick, the most successful NFL coach of the present era, and tomorrow's battle between the New York Giants and his own New England Patriots for the gaudiest prize in American sport has nothing to do with revenge. "This game is about this team, this year," he insists. The past doesn't matter. And anyway, "there aren't really a lot of us who were actually involved in that game."
Ah yes, "that game". It too was a Super Bowl, no. XLII in the Roman numerals the league employs to add even more gladiatorial spice to the occasion. It was also one of the most memorable, a 17-14 win for the Giants thanks to a touchdown with just 35 seconds on the clock.
The outcome wasn't merely an upset for the ages. It robbed the Patriots of a 19-0 perfect season, that would have statistically sealed their place as the greatest team of the modern era. Four years on, the same two opponents will take to the field for Super Bowl XLVI.
Belichick is right to point out that, apart from himself and Tom Coughlin, his opposite number at the Giants, and the two quarterbacks, Eli Manning and Tom Brady, few of the players in 2008 will feature this time (the average career length of an NFL player is only three and a half years). But whatever he says, revenge will be on giant dishes invisibly lining the touchline at the Lucas Oil Stadium in Indianapolis. And it won't be eaten cold.
In fact, nothing about Super Bowls these days is ever even tepid, let alone cold. The game is the biggest single sporting event in the Western hemisphere. Its date on the first Sunday in February is a part of the national calendar to rival Thanksgiving or the 4th of July. In truth though, it is a week- long extravaganza, a celebration of how the Gridiron colossus bestrides American sport.
The NFL claims to be the richest professional sports league on earth. True, its serene progress was briefly slowed by an 18-week lockout before the 2011 season, as owners and players fought over how to divide $9bn (£5.7bn) of annual revenues. Gradually though the realisation dawned there was more than enough for everyone. Only one pre-season game was lost, and the NFL today is more popular than ever.
The Super Bowl is its most glittering showcase. The last four of them have been four of the five most watched broadcasts in US history (the fifth was the final episode of M*A*S*H in 1983). No detail is too small to warrant a news story. This week The Wall Street Journal informed its readers that during the game, the estimated 110 million-plus TV audience will consume, inter alia, 13.2 million pounds of pretzels, 45.8 million pounds of potato chips and 111 million gallons of beer.
The going rate for 30-second commercials during the game (the ads, incidentally, are a minor cultural phenomenon in their own right) is seen as an important barometer of the nation's economic health. This year's spots cost a record $4m each. Maybe the recession finally is over.
Another, smaller, innovation tells a similar story of the Super Bowl's success. The Tuesday before the game is traditionally Media Day. It used to be limited to players and reporters. This year the NFL spotted another little earner, and sold 7,300 tickets for fans to sit in the stands and follow proceedings through special earphones. The tickets went on sale online for $25 and sold out in an instant. By Tuesday, touts outside Lucas Oil Stadium were hawking them for $45 apiece.
Americans, it seems, simply cannot get enough of what they call "football". Roger Goodell, the league's Commissioner, is now talking of adding two new franchises to the existing 32. At least one, and maybe both, will go to Los Angeles, the country's second largest metro area, which astonishingly has no team at all right now, and push revenues higher still.
For the first time too, the NFL will directly address during this Super Bowl the one truly dark cloud hanging over the sport – the risk of concussions, and long-term brain damage suffered by former players, some of whom are suing the league for negligence. In the interval between the final two quarters, a 60-second spot will run, illustrating the improvements in rules and equipment over the decades and conveying that the old indifference to injury is gone, that player safety is now the top priority. It ends with the veteran Baltimore Ravens linebacker Ray Lewis saying: "Here's to making the next century safer and more exciting. Forever forward. Forever football."
And after all the hoopla, football tomorrow is what it's all about. Only rarely are Super Bowls an anti-climax, and if the Patriots' rematch with the Giants is is only half as good as "that game", two evenly matched teams will have offered up another feast.
According to the Las Vegas bookmakers, the Patriots are again favoured, but by a bare three points. The public however is betting on the Giants – meaning that it could be an expensive day for the bookies. As usual, the performance of the two quarterbacks will be key.
In 10 years with the Patriots, Tom Brady already has appeared in five Super Bowls, winning three of them and is considered the pre-eminent quarterback of his era. But Eli Manning, his opposite number, is having arguably his best season yet, while the Giants have hit peak form at the perfect moment.
Two questions dominate. Can New York's fearsome defence repeat its performance of 2008, when it harried Brady throughout, knocking him out of his rhythm? If so, then the Giants will again prove the Patriots' nemesis. But if Brady is given the protection to work his magic, New England will probably prevail.
The Patriots two tight ends, Rob Gronkowski and Aaron Hernandez, have been a record-breaking scoring partnership this season. Can they continue in that vein tomorrow?
If so, they will have lived up to the nickname bestowed on them by an adoring New England press, of "The Boston TE party".
