I don't get the genius angle on this post OP. The fact is Rhule drastically improved Temple and Baylor during those short stays and didn't stay to reap the benefit of improving his winning % over multiple seasons. Do you think his % would be higher if he'd stayed at Baylor for 10 years? I do. Will he improve Nebraska similarly? I don't know, but I know he's better than Mike Riley.
You are just guessing when it comes to thinking Rhule would have more wins under his belt if he would have stayed longer at Baylor. There is no way of proving it because he left. I think he is what his record shows he is. Hasn't disproved in Lincoln so far.
Let's get to the three seasons Matt Rhule hangs his hat on.
2015 Temple (his breakout year) 10-4 Lost to #9 Notre Dame, South Florida, #19 Houston (Conference Champ.) and Matt Campbell's Toledo (Bowl) Beat an unranked Penn State and #21 Memphis (all ranked opponents are listed)
2016 Temple 10-4 Lost to Army, Penn State and Memphis (all unranked) and the team lost to Wake Forest in a Bowl with Ed Foley coaching. Beat the only ranked team they played that year #19 Navy (conf. champ.)
2019 Baylor 11-3 Lost to the only ranked teams they played that year #10 OU in Waco, #6 OU, in OT (conf. champ.) and #5 Georgia (Bowl) Was the Big 12 down that year? I can't remember, but Texas and K State were both unranked when Baylor played them. Won two OT games in the regular season Texas Tech and TCU (I think this was a pretty good season and would be ecstatic with the same results. with the Huskers. Just wish I knew how good the Big12 was that year)
I think his record shows he has trouble beating ranking teams and he has done nothing to disprove this during his time with the Huskers.
