That No. 7 seed hangs by a pinkie now, assuming the Pac-12 refs are done tap-dancing all over the Buffs’ fingers as they dangle from the postseason cliff.

On the plus side, a win at the league tourney in Vegas probably launches CU’s Bracketville train in Cleveland (Hi, Mel!), Tampa (groovy), Greensboro (less groovy) or Albany (yikes), pending results from other corners of the hellscape.

But what if the Buffs’ uptown funk stretches to the Pac-12 Tournament? What if CU’s current losing streak hits five before Selection Sunday, now just a week away?

“Then they’re probably in an 8-9 game,” longtime CBS Sports bracketologist Jerry Palm told The Post before CU’s 74-72 overtime loss at Utah on Saturday. “Maybe.”

For once, there’s no bubble in Tad Boyle’s world this month — just bumbling and stumbling down the stretch.

Despite a four-game losing slide in which the Buffs and the broad side of a barn have become perfect strangers, CU (21-10, 10-8 Pac-12) remains in good shape as far as NCAA Tournament bona fides go, thanks to neutral/road tilts in November and December against the likes of Kansas (loss), Dayton (win), Arizona State (win) and Clemson (win). When in doubt, kids, schedule up.

CU’s ranking in the NET, the computer power ranking for which the committee wonks kicked the Ratings Percentage Index to the curb, was a healthy No. 23 as of Saturday morning. The Buffs haven’t wavered out of the 15-25 range since Valentine’s Day. They’re in. No drama.

That is, unless your end game is getting out of the first weekend of the Dance.

Which means, ideally, navigating a path out of the same 8-9 sand trap that Boyle’s Buffs found themselves in during the 2016 and 2014 tourneys.

As of Saturday, CBS Sports’ projection had CU slotted as a 7, in Cleveland, against 10th-seeded Indiana (19-12). Palm says that in order for the Buffs to stay on that line, they’ll have to stop the bleeding with at least one more victory this week. Somehow.

“If (the Buffs) win the tournament, that’s got to be worth a couple lines,” Palm said. “They’re not going to be a 2 or anything, but their realistic upside is the bottom part of the top 25. So a 5-6-7 (seed) is (ranked) 17-25.

“I’ve had them as high as a 4. But the realistic upside is 5 to 7.”

The realistic downside, to be fair, is still pretty darned good, especially as a 7 seed would be the best for any CU squad since the tourney expanded to 64 teams in 1985.

It just feels like a kick to kidneys compared to the vista of 15 days earlier.

“They could still be a 7,” Palm continued. “You have to keep in mind that a lot of those teams are going to lose their last game. … Everybody else is going to be losing, too.”

The Buffs went into the weekend with a 7-4 record in what the NET considers “Quad 1” games, which are defined as home games against NET teams ranked 1-30, neutral-site games against NET teams ranked 1-50, and away games against NET teams ranked 1-75. CU went into Saturday tied with Oregon for the most Quad 1 victories among Pac-12 programs, with seven each.

Yeah, the shots aren’t falling. But neither is the sky. You hope.

“The only thing you could really root for is your nonconference opponents, but they don’t have that many games left,” Palm said. “There aren’t enough teams to actively root against. Just go out and win your own stuff.”
