The NCAA screwed this up badly. The video challenge rule was never intended to fix scoring errors. For if a coach is out of challenges are they then arguing that the scoring error cannot be corrected and that there is no recourse?
The following rule is what actually governs scoring errors and was ignored by the committee in their statement "3.11.2 Error by Timekeeper and/or Scorers. Any error not resolved by the referee shall be arbitrated by the tournament committee." As there is no way for a tournament committee to meet before the next match begins it is clear that rulings can be made after the fact when so warranted.
If you've followed the Dardane's-Stieber misscoring and my subsequent banning then you know that I blame the coaches 100%. Why, you may ask? Because clock/riding time/scoring errors occur frequently and often go unnoticed. For instance, Nick Dardanes had another match misscored in the National Duals, but it wasn't noticed nor corrected because it didn't affect the outcome. I was at the Nebraska home dual on 2/10/2005 when Okie St won because of a scoring error, 19-18.
Referee's do their best but the burden of getting the calls correct is tough enough without also having to keep track of the score. And we all know that scorekeepers/timers are often hastily drafted and poorly trained.
The only way for teams to prevent these kind of commonplace foulups is to assign an asst coach to track the clock/riding time/score. Now the NCAA needs to determine what is their policy for correcting fouled scorekeeping and then tweak it to make it work.
