This is no time to be a killjoy, not after the Creighton Bluejays advanced for the first time to the Sweet 16 since the NCAA Tournament expanded in 1985, and for the first time to the regional semis since the 25-team field in 1974.

This is no time to be Hatin’ on Creighton, no sir, no ma’am.

Hardly a perfect team, hardly a team that has opponents cowering in fear, hardly a team that reminds anyone of Bobby Knight’s unbeaten 1976 Indiana Hoosiers … but all they ask you to do in March is survive and advance, and the Jays survived Ohio in the West Region at historic Hinkle Fieldhouse and advanced on Monday night.

Dance, Jays, dance. You’ve made your fans and your school proud.

And look, we have witnessed so much Madness so far that who is to say these irrepressible Jays can’t dribble all the way to One Shining Moment on the first Monday night in April?

And hey, five double-digit seeds have gotten to the Final Four — four 11s and one 10. Villanova was an 8 seed when it shocked Georgetown in the 1985 championship game.

One problem, Creighton:

A monster will be waiting for you.

A 28-0 Gonzaga monster that is driven to complete the first undefeated season since Knight’s Hoosiers.

Sorry, Creighton.

In other words, enjoy this while you can.

“My mentality: I’d expect to win,” Creighton star Marcus Zegarowski said, “That’s who I am, I’m always gonna expect to win, I don’t care who I play.

“I know they’re a great team, I know they have no weaknesses, I know they haven’t lost, but that doesn’t change my mentality. I’m going on telling my guys, ‘They still gotta play us.”

Look at it this way: all the pressure will be on the Zags. All of Indiana will be rooting against Gonzaga, and rally to your side, especially if you can stand up to the bully.

History tells us that David CAN beat Goliath, right?

Let’s see if you can play the perfect game against the perfect team.

Because, no disrespect intended, that’s what it will take.

“We’re not done yet,” Zegarowski said. “This is just a start, and we look forward to our next matchup with Gonzaga.”

On Monday night, Zegarowski (20 points) won the point guard duel with Jason Preston (1-for-10 shooting, 4 points).

Preston, hounded by 6-foot Shareef Mitchell and 6-5 Denzel Mahoney, was nowhere near his playmaking self. It is called cutting off the head of the snake. The Bobcats shot 31.8 percent and 23.3 percent (7 of 30) from downtown Athens.

Zegarowski played care free.

The Jays played with more swag, composure, poise and togetherness.

The Bobcats, led by Mark Sears, cut their deficit to 65-56, but a dagger floater by Zagarowski finished them.

“They were hungry to play,” coach Greg McDermott said. “This group’s been together a long time and they know that I trust ’em, and I think they trust each other.”

Zegarowski’s fourth 3 in four tries extended Creighton’s lead to 52-31 with 14:41 remaining.

The Jays endured a cold spell and the Bobcats clawed back to within 56-43 with 8:09 left. An emphatic alley-oop flush by Christian Bishop (12 points, 15 rebounds) undoubtedly frustrated Athens, Ohio native spectator Joe Burrow.

The Bobcats missed 10 of their last 11 shots and scored four points over the last 7:39 of the first half. The Bluejays (50 percent shooting) uncharacteristically attacked the basket with little resistance. A 20-4 run gave them a 39-24 halftime lead.

“Once we get stood and get out and run in transition, we’re tough to guard, and that’s what we have to do moving forward,” Zegarowski said.

Someone reminded Zegarowski of Gonzaga scoring 62 points in the second half of a 103-92 victory in 2018.

“I do remember that game,” Zegarowski said. “To beat them we have to play really, really well for 40 minutes. We can’t have those stints where we take bad shots or we miss an assignment … we’ll be ready.”

Dance, Jays, dance. While you can.

Let the Jays celebrate. While they can.
