I love Campbell, but it's not even a competition between him and Ruhle as to who has done better at their current job. Like not even a little.
Do you know how difficult it is to change a losing culture and mindset to a winning one?
Look at Baylor's record before Rhule took over:
2012 8-5
2013 11-2 Big 12 Title
2014 11-2 Big 12 Title-Tied
2015 10-3
2016 7-6 (Grobe)
Not a single losing record in the 5 years prior to Rhule taking over and two Big 12 titles which means that he had guys on his team when he got there that knew what it took to win. ISU did not have that luxury when we hired Campbell.
On top of that, go look at the recruiting classes for those years:
Big 12 Rank for Recruiting classes
2012 - Baylor: 3 vs. ISU: 8
2013 - Baylor: 3 vs. ISU: 9
2014 - Baylor: 3 vs. ISU: 10
2015 - Baylor: 5 vs. ISU: 9
2016 - Baylor: 5 vs. ISU: 8
