I think ALL BYU fans would, in the words of the OP, "...love to see BYU desecrate Boise's field 58-0 or something."
But - do we all think that's actually going to happen? Or even possible?
No disrespect to Boise. I'm sure they'd love to beat BYU 58-0 too, but that's different than expecting or even predicting it. And no one is predicting a BSU beatdown.
