Sheer athleticism of those SC WRs is the primary reason why Troj beat Oregon in 2011.
Oregon got shocked by how good the USC receivers actually were. USC's defense caught them off guard early as well and created some turnovers. By the time Oregon adjusted, it was too late..............................barely.
Essentially, USC beat Oregon the only way that they could with that team. They built a big early lead and then hung on for dear life.
