with a 2-3 record and come out reasonably healthy, I think they will be okay. The schedule is pretty reasonable over the final 2 months of the season. Boise State and Utah on the road will be tough but the other 5 games are all winnable.
The first two games are crucial though, if BYU comes out 1-1 and looks respectable in the loss (probably to Arizona) then I think they will have a solid year and a winning season but if its a slow start and 0-2 out of the gate then the season could get away from them and we could be in for another tough season.
