I'm not sure why you think that I think Utah would be overcoming overwhelming odds.
I do think the timing of injuries makes for a bit tougher adjustment by Utah, but that's it. Utah still has a decent running game, and the passing game has rarely been a big part of Utah's offense this year. So, no, I don't think the odds against Utah are overwhelming. To the contrary, I personally think the odds are against BYU. I think if BYU wins, they will have beaten one of the best Utah teams to date.
