You assume SC is a bubble team. They aren't. The more apt question would be howl the Oregon State win affects UCLA's tournament chances.
SC still has the best overall record in the conference. If you were ranking Pac-12 teams for the tournament, they would be (1) Colorado, (2) SC, (3) Oregon, (4) Oregon State, and (5) UCLA.
UCLA's obviously the only true Pac-12 bubble team, at least at my first glance. Go Baby Bears! ORE ST helped them into at least a probable play-in game by winning the tournament.
