Utah caused enough problems of its own Saturday, but Craig Robinson deserves some of the blame for another loss that moved the Utes’ season toward the crumbling stage at the halfway mark of the Pac-12 basketball schedule.

If Robinson had succeeded as Oregon State’s coach, OSU’s Tres Tinkle probably would have become a Ute and none of this stuff would have happened in the second half of the Beavers’ 81-72 victory at the Huntsman Center. After a dreadful first half, the Utes rallied repeatedly, only to have Tinkle make one momentum-killing play after another.

A son of OSU coach Wayne Tinkle, the junior forward likely would have signed with Krystkowiak, his father’s teammate and former boss at Montana. But then came the opportunity to join his father in the Pac-12 after Wayne Tinkle replaced Robinson at Oregon State.

Tinkle finished with 31 points, apparently not fazed by chants of “Daddy’s boy” from the student section. His production included a 3-pointer when Utah trailed by six, a rebound basket when the Utes were within five and then the dagger – from about 5 feet beyond the 3-point line with the shot clock winding down, Riley Battin’s hand in his face and Utah down by four with 1:43 remaining and the building sounding louder than any time this season.

“That’s a moment-of-truth play,” Ute coach Larry Krystkowiak said, “and I don’t know how we guard it any better.”

Krystkowiak then cited many aspects of the Utes’ game that need work, after his team went from being alone in second place in the Pac-12 and leading Oregon by 14 points in the first half Thursday, to falling too far behind Oregon State (14-7, 6-3) and eventually dropping into a three-way tie for fifth. “We’ll fix it,” said junior center Jayce Johnson. “We can still do this thing.”

But life may get worse for the Utes (11-10, 5-4) instead of better, because the second half of their conference schedule is more difficult.

That’s why the Utes desperately needed Saturday’s game, a theory that fails to explain why they played so timidly. The Beavers grabbed seemingly every loose ball, drew a bunch of fouls and kept the Utah from scoring. The Utes missed 10 straight shots in the first half, partly because they passed up decent looks and then fired wild shots in an effort to beat the 30-second clock. Utah had four shot-clock violations in the game.

“I can’t live with ineptitude for us offensively,” Krystkowiak said. “Shot-clock stuff, that’s on me as a coach, to figure out what it was.”

Staging the annual Huntsman Strong game for cancer research support on the one-year anniversary of Jon M. Huntsman’s death, Krystkowiak wanted to honor a major influence in his life with a determined effort by Utah. That happened only in the second half, after he appealed to his team with a Huntsman-themed speech. “That’s where we’ve got to draw the line, in terms of effort,” Krystkowiak said in the postgame news conference.

Krystkowiak liked his team’s response, and just imagine if the Utes had completed their comeback after trailing by 15 points early in the second half. Huntsman’s frequent messages to the team usually ended, “Go big!” The players and coaches wore patches with that phrase Saturday, and Utah’s rally carried out that wish.

The problem was that Tinkle went bigger.

If not for him, Ute freshman Timmy Allen’s season-high 24 points and Sedrick Barefield’s 19 might have been enough to give Utah a memorable win. Instead, the Utes were left to lament how they played only halfway acceptably, on an important day for the program.
