March Madness lives on. Following the cancellation of the NCAA Tournament, The Post projected the final bracket and will spend the rest of the week presenting round-by-round results produced via online simulation, thanks to our friends at whatifsports.com.

This was the NCAA Tournament everyone imagined.

Upsets galore. Favorites going down. Double-digit seeds busting brackets.

The regular season was defined by parity and unexpected results — seven different top-ranked teams in the Associated Press poll — and so far, so has The Post’s simulation of what the Big Dance would’ve looked like if not for the spread of coronavirus forcing the NCAA to cancel it.

The second round saw two No. 1 seeds (Gonzaga and Kansas) lose after No. 1 Dayton failed to get out of the first round, the first No. 16 (Winthrop) reach the Sweet 16, two other double-digit seeds advance (No. 11 Wichita State and No. 12 East Tennessee State) and just one region — the South — go chalk.

Baylor, an 81-76 winner over LSU, is the only remaining top seed. The last time at least two No. 1 seeds failed to get to the Sweet 16 was 2004. Three have never failed to reach the second weekend since the tournament went to 64 teams in 1985.

After becoming the second No. 16 to knock off a No. 1, Winthrop made history by knocking off No. 9 Oklahoma, 78-69. The Big South champion took control with a 16-3, second-half run and held the Sooners to just 25 second-half points, earning an East Regional semifinal matchup with Big Ten tri-champion Maryland, the fourth seed, at the Garden.

That was only the beginning of the madness. The top seeds in the West, Gonzaga, and the Midwest, Kansas, went down to underdog nine-seeds, Marquette and USC, respectively.

Kansas, winner of the Big 12 which ended the regular season atop all the national polls, seemed to be in control, up 14 early in the second half and by eight with 2:25 left. But USC closed on an 11-2 run, getting within one on a Onyeka Okongwu follow with 17 seconds left. After Devon Dotson missed the front end of a one-and-one on the other end, Elijah Weaver sank a jumper from the foul line, leaving just two seconds left.

Marcus Garrett’s desperation heave was off, marking the second time under Bill Self that Kansas failed to reach the Sweet 16 as a No. 1 seed. Behind Markus Howard’s 32 points, Marquette led the entire second half in sending Gonzaga home early, 89-86, just the first time the Zags didn’t win two games in a tournament since 2014.

The two other double-digit seeds to advance hardly broke a sweat. Twelfth-seeded East Tennessee State, the Southern Conference champion, cruised past No. 4 Wisconsin, 91-70, shooting 52.5 percent from the field and starting the second half on a 15-1 run to take a 20-point lead.

The Buccaneers, who last won a tournament game in 1992, will meet USC in a Midwest Region semifinal nobody could see coming. They have advanced this far just once, back in 1968.

In St. Louis, No. 11 Wichita State blitzed No. 3 Creighton, 94-78, crushing the undersized Bluejays on the glass, 42-29, and shooting 52 percent from the field. The Shockers will meet No. 2 Michigan State in the Sweet 16, the lone top seed from the Midwest to survive. The Spartans ended seventh-seeded Virginia’s title defense, manhandling the Cavaliers, 63-46.

It sets up an intriguing Sweet 16, with three Cinderellas — Winthrop, East Tennessee State and Wichita State — premier power-conference matchups like Duke-Villanova, Baylor-Louisville and Seton Hall-Florida State, and the decimated Midwest Region, featuring Michigan State and three surprises.

Imagine the fun that would’ve been had. What a shame.
