Keegan got plenty of PT that season (even moved into the starting lineup when CJF got hurt, IIRC), he was solid but not a star like he was the following season. Kris played sparingly and, when he did play that season, looked like a guy that should only be used sparingly.Thats not even remotely close to reality.
That Oregon team was no where near the level of teams like Baylor or even Gonzaga in terms of quickness and athleticism.
Oregon got blown out the next game by USC who then got blown out by Gonzaga who turned around and got blown out by Baylor.
Its not that that particular game was a choke its that the season was a choke.
Fran played Connor, Jbo and CJ all year, and left Toussaint, Perkins and Kris on the bench and didn't start Keegan.
He surrounded Garza with a bunch of other bad defenders when Luka Weiskamp and Keegan could have carried two poor shooting guards if those guards could have played defense.
Iowa got destroyed by Oregon because of the complete lack of ability to defend by the back court.
Guys like Izzo sacrifice wins early to gain give their young talent the experience necessary to maximize potential at the end of the season. Fran usually takes the opposite approach and the results are consistent.
Oregon was far more athletic than Iowa, which is the only thing that's relevant here. If you can't see that, then you are blind. It's not debatable. They won the Pac12 regular season crown and were a good team, as was the USC team that beat them. If they benched CJ and JBo in favor of Toussaint and Perkins, like you suggest, maybe the offense is still good but I'm skeptical - I think teams would sag way off of Toussaint and Perkins, crowd the lane, which would hamper Garza's effectiveness.
