If CU lights up the scoreboard on them, it'll make it look like CU really is a lot better than BYU now. But you could also chalk that up to BYU breaking Utah's will for the rest of the season and Utah's D not caring as much anymore after their own offense failed to do their part to put up any more points in the 2nd half to secure a win.
Regardless of what happens, it would be nice to see BYU get some style points over KU, but that will be a very very tall task.
