In what world

Do you foul the opposing player when you have good defensive position, the opposing player is 80 feet from the basket, you are up three points, and there is 2.6 seconds to play? I'll take an off-balance halfcourt heave (or at least letting him dribble for more than 0.7 seconds, which would have not allowed enough time for the game-tying putback) over this series of events:

For emphasis, the moment, screen-grabbed. In reality, Ducks were lucky to have even 0.7 seconds go off the clock, as you can see the white of Will Richardson's armband already reaching in after only 0.1 seconds (top right of picture). The ESPN graphics operator hasn't even managed to give Oregon its 80th point yet:

Dude likely ain't getting to half court, and there's a lot of white jerseys in front of him. You could argue that Prince Ali (real name, no gimmicks, #23 at the bottom of the screen) might be running free for a pass, but that's only because the guy who is supposed to be guarding him (Victor Bailey Jr.) stopped playing because he knew Oregon was fouling.

Full context of the sixth-largest last-minute comeback in NCAA history -- and I'm guessing the five games with a larger deficit involved some missed free throws by the team in the lead: 

UCLA shot 3 of 19 from the three-point line during the first 37 minutes of this game. They went 5 of 5 from three over the last 2:21, and also made all three free throws when fouled shooting a three-point attempt.
