Quinn was 20-36 when LL took over the program in 2015. In 2013, two years before LL started, Quinn led the Bulls to 2nd in the East, an 8-4 regular season record and a bowl game.
So...to recap...
UB in 2013...8 wins and a bowl game.
UB in 2014...5 wins in 11 games (blame KSU)...Quinn fired before the season ends.
Kansas...since 2010, the most wins they have had in a season was 3. They have finished 10th in the conference 9 out of the last 10 years (they finished 9th in the other season).
in conclusion, comparing what LL is taking over now relative to what he took over at UB...there is no comparison. The data above tells the story.
I would think that Kansas is probably the worst job in P5...or certainly on the very short list of worst P5 jobs at the moment. UB, when LL took over, was a middling MAC team in a middling G5 conference.
