As previously mentioned, Duke destroyed teams, really ran up scores that year. UConn won games by a closer margin.
That said, from my understanding SRS just takes into account how dominant a team appears to be not necessarily how good they are. There are so many of factors not accounted, such as style of play, coaching philosophy, injuries, when bench is cleared, etc.
For example, I imagine UVA would score relatively poorly, bc they historically rarely win games by a large margin. But as they say, a 10 point win by UVA feels like a 20-30 point win.
