We should have known what was coming in college basketball. The opening day of the season gave us a big hint.

Stony Brook fell behind George Washington 22-0. Would the Seawolves, like, score this season? Relax. They tied the game on the last second of regulation, won in overtime. “We knew (George Washington) was going to make a run,” coach Jeff Boals would later say. “We didn’t know it would be 22-0.”

The same day, Baylor led Texas Southern by 17 points with 14 minutes left. The Bears were 56-0 all-time against SWAC teams. That score seemed to make 57 a lock, right? Wrong. Texas Southern, 72-69.

The Year of the Comeback had begun.

From then to now has been one long series of flips, often followed by flops. Missed free throws, game-changing 3-pointers, ill-timed turnovers, foul luck. Anything, everything. Happens every season, but this seems like an epidemic. By KenPom figuring, there were 58 games won last season won by teams whose deficits gave them less than two-percent probability of survival. There had already been 45 this season through Saturday, and we’re not even in February yet.

Consider this past weekend.

On Sunday, Rider fell behind Marist by 16 points with just over 14 minutes left, then went on a 16-0 run and ended up winning 86-85. Rider leads the MAAC with a 6-1 record, and trailed by double digits in three of the six victories. “We make life interesting,” coach Kevin Baggett said.

On the same day, Cincinnati trailed Temple by 14 points in the second half, then rolled past the Owls to win. For more than 13 minutes in the second half, only one Temple player scored a field goal.

On Saturday, that was Clemson not making a 3-pointer all game, but still leading at North Carolina State by six points with 26.5 seconds left . . . then losing on — yep — Braxton Beverly’s 3-point buzzer-beater. The door was ajar because Marcquise Reed — Clemson’s all-time best free throw shooter with an 86.1 career percentage — went 0-for-4 from the line in the last seconds. “He’s made thousands of free throws for us to seal games,” coach Brad Brownell said. “I feel bad for him.”

That was Missouri leading LSU 70-56 with 2:14 left . . . and losing in overtime. Skylar Mays scored nine points in a row, and Missouri doomed itself with three late turnovers. LSU coach Will Wade turned to his golfing past to describe it: “It’s like I told our guys in the locker room, we’re out of mulligans after that.”
