No one thinks it's impossible to hit the lottery if Bronco is fired. But the odds are very, very bad. Look at the college football royalty that have gambled and come up craps.
Firing Bronco would be a fools bet. Easy to bet brave with other people's money...Holmoe doesn't have that luxury...And BYU isn't in the position to work through 2 or 3 or 4 duds trying to find a stud...as Tennessee has...and Florida...and USC...and Texas...and Notre Dame...
Living in the no man's land between P5 and G5 doesn't give BYU the luxury of playing fast and loose.
Be careful what you wish for. Fire Bronco and live the Nebraska curse...possibly multiple times...
