The short story is that Boise State made an incredible, improbable last second shot (actually last sub-second shot, the inbounds play began with 0.8 second remaining in the game), which the officials ruled did not occur because the clock did not start at the right time.
Here is what the game official later said:

The NCAA Rulebook says (p. 62 here in PDF):
When an obvious mistake by the shot-clock operator has occurred in failing to start, stop, set or reset the shot clock or when a shot clock has malfunctioned, the mistake or the malfunctioning problem may be corrected in the shot-clock period in which it occurred only when the official has definite information relative to the mistake or malfunctioning problem and the time involved. When a timing mistake or malfunctioning problem occurs that gives a team more time than that team is entitled to, any activity after the mistake or malfunctioning problem has been committed and until it has been rectified shall be canceled, excluding any flagrant foul or technical foul.A lot hinges on the phrase "obvious mistake" here, but it seems clear from the ESPN replay and timing in the video above that there was no obvious mistake. In fact, there was no mistake at all.
Perhaps Boise State should protest the result?Just for kicks, I stopwatched the Webb shot three times, and got 0.62, 0.66 and 0.68 seconds from catch to approximate release— Andy Glockner (@AndyGlockner) February 11, 2016
The NCAA has that covered (p. 62 of its rule book):
The NCAA Men’s Basketball Rules Committee does not recognize or allow protests.The referees botched this one pretty good. Although Boise State will not get an earned victory, hopefully the Mountain West or NCAA has some way to sanction to officiating crew.
