Very few programs replace their exiting somewhat successful coach with a better coach on paper.
In his last 2 seasons at SIU, and his first 6 season at Illinois, Weber had a .744 winning %, won 3 conference titles, finished 2nd in the Big 10 another time, went to the Sweet 16 twice (at 2 schools), and the Final Four.
Nobody available out there that K-State had a realistic chance of hiring had that kind of resume.
You can rub one out all day long and twice on Sunday in regards to Gottlieb or Pearl. But in terms of guys like Doug, if those kinds of hires go South, they typically not only go off the road, they go through the ditch, into the woods, explode and nobody finds the burnt out wreck for 20 years. Very few, well, likely NO major conference school AD and President is going to take that chance. In regards to Pearl, while that would have been fun (just like Gottlieb) no major conference school AD and President is in the mindset to tangle with the NCAA given their current mode and mood.
