After all, what could possibly top putting America's biggest sporting party in the U.S. party capital?

In the week long buildup to Sunday's championship game Las Vegas -- with the help of a headline grabbing romance between Kansas City Chiefs Travis Kelce and mega popstar Taylor Swift -- delivered the glitz and pizzazz as promised.

Now the spotlight locks onto the Chiefs and San Francisco 49ers who will be expected to come up with a finish worthy of the biggest show on the strip.

The game could be a watershed moment for the NFL with predictions it might produce the biggest viewership numbers since Neil Armstrong set foot on the moon.
