So, just make shit up?
Kelly's salary is over 8k, he left for bigger pay day, Kirk didn't.
Kyle Whittingham coaches at a much smaller school in an even weaker conference.
Mike Gundy makes 7.5+
Kris Klieman, the KST coach, is who I assume you mean, is on his first contract with the school and after the past few seasons, he's in line to make much more than Kirk Ferentz and I'll eat my shoe if his next contract isn't much higher than what Kirk has gotten.
Barta made an unpopular deal with the fans that has actually played out very well for Iowa in hindsight, if you don't see that, you're just biased.
at least do some research, it's all I ask
