Why not hope for something more? And also, there's more to this than overall winning percentages. Bronco had a better winning percentage than Lavell, but Lavell accomplished more things of national consequence than Bronco did (subjectively speaking). KS may not improve on our overall win%, but it's entirely possible he gets us and keeps us ranked more often, goes to a NY6, maybe has 1 or 2 11 or 12 win seasons etc.

Believe me, BYU has not accomplished everything it is capable of accomplishing.
