I can't help but wonder how the Pac-12 Conference expects us all to believe that the blunder that took place earlier this season with instant-replay was an isolated incident.

The conference said that it reprimanded "certain" people involved. But it wouldn't say who was punished or what the punishment was. The Pac-12 just wants us to trust it did it. Also, same day, the conference publicly fined Arizona State defensive coordinator Danny Gonzales $5,000 for his criticism of Pac-12 officiating.

Selective transparency isn't transparency at all.

The Pac-12 is vowing to publish a comprehensive instant-replay guide, and they're promising that unqualified individuals won't be involved in steering the outcomes of games going forward. But fans are skeptical and the media isn't going to stop asking questions.

Washington State coach Mike Leach said this week: "Those that have a voice have to speak for those of us who are silenced."

On that note, I keep thinking about the text exchange between Leach and Pac-12 General Counsel Woodie Dixon that was exposed in a recent public record's request.

In the texts, Leach accused Dixon of phoning Cougars' staff members in the press box during a Oct. 31, 2015 home game against Stanford. The Cardinal coaching staff apparently complained about the noise inside Martin Stadium that night. According to that text exchange Leach believed that Dixon ordered WSU to turn the band noise down because, "they were playing too loud."

Also, Leach wrote to Dixon via text: "Why can't I help wondering, if you're trying to manipulate wins and losses?"

It's something we've all wondered after it became apparent that Dixon had overstepped his duty in what conference commissioner Larry Scott called, "a mistake." The conference insists it was an isolated incident, but refuses to release instant-replay reports from games. That Leach is apparently still fuming about that 2015 game nearly three years later makes you wonder.

After what we've learned in the last couple of weeks, I'm wondering how widespread Dixon's meddling was. That text exchange caused me to look back at the 2015 game between WSU and Stanford that Leach referenced. Particularly, because a couple of instant-replay decisions went against WSU in that game.

Incident No. 1 involved a pass play in the second quarter in which Washington State intercepted a Kevin Hogan pass and returned it for a pick-six touchdown. The call on the field was overruled, however, by the instant-replay review. Hogan's pass was deemed an incomplete pass instead of a Cougars' interception and touchdown. What struck me about the review was that the replay footage available appeared to be inconclusive, and failed to meet the threshold for a reversal.

That's a barstool debate, though. If that play had happened in a vacuum I probably wouldn't even write about it. But there was a second, more glaring instant-replay incident in that game, that made me wonder if Leach's text message to Dixon was loaded with truth.

Remember, Dixon has no formal officiating training, and we now know he meddled in the Sept. 21 game this season by playing wanna-be referee during that game. In fact, Dixon wasn't even working that night in the booth. He was watching the game and telephoned in and overruled both the in-stadium replay crew and the league's centralized command center working the WSU-USC game.

Incident No. 2 in the 2015 game involved an apparent Christian McCaffrey fumble. It looked like a fumble. The broadcast team thought it was a fumble. McCaffrey appeared to think it was a fumble too based on his body language. But the instant-replay review deemed it would remain Stanford's ball. It was an obvious instant-replay error. Look for yourself here:

It sure looks like a fumble. It should have been WSU ball, with a 22-10 lead and 4 minutes left in the third quarter. Instead, Stanford retained possession and went on to win 30-28.

Given the accusation leveled by Leach, and what we know about Dixon's recent actions, I have questions about whether the integrity of officiating was compromised more than once. I can't help wonder if the conference may have been protecting McCaffrey, who rushed for 2,019 yards and finished second in the Heisman Trophy vote that season. Or maybe the conference was protecting Stanford, which was 6-1 and ranked No. 8 in the country that night.

This is what the Pac-12 has done to us all, isn't it?

Its raised doubts and questions, and turned us all into conspiracy theorists. Not rooted in paranoia, though. Rooted in the fact that a troubling incident occurred that has eroded the trust of the public in the Pac 12 Conference. Also, that the conference has raised only one bit of evidence to support itself.

Its word.

Washington State could have won the 2015 game had it made a short game-winning field goal at the end of regulation. The Cougars missed it. They lost. That's on them. But the fact that we're all left to wonder if the Pac-12 Conference has a lengthy issue with the integrity of its competition is on only one entity -- the conference itself.

Questions I asked the Pac-12 on Friday: Was Woodie Dixon in the instant replay booth for the Stanford-WSU game in 2015? Was he in the centralized command center? If not, did Dixon call in? And will the conference make the replay report for that 2015 Stanford-WSU game available to the public so we can see if Dixon overruled the replay officials?

Andrew Walker, a spokesperson for the Pac-12, got back to me via email. He wrote: "The conference made an announcement earlier this week and I would refer you to that release and the conclusion that what occurred was an isolated incident as well as the other information contained within the release."

Basically, there's nothing to see here. Take their word for it.
