Utah's tradition of beating BYU in Provo...
6 of 8 over the past 16 seasons. That is 75% if I do my math right.
Now, what was BYU's strong tradition again?
Utah has won more games over all, has a higher winning % overall, owns a 20 game lead in the rivalry, has won more bowl games overall, has a much higher bowl winning %, has a much higher winning percent against the BCS or even just ranked teams, has gone to 2 more BCS bowl games than BYU - read BYU 0 (zero).
BYU is the perenial September National Champs and September BCS busters. That is tradition.
