McCarney won 39.7% of his games at ISU, which is not even at the (bad) historical rate ISU has.
Mac took over a historically bad program and turned the program into a consistent winning program and Bowl participant. Mac coached ISU to 5 winning season in the last 7 years he was at ISU. Jamie fired Mac for a single 4 win season. Jamie Pollard coaches have had 1 winning season in the 10 since.
It always blows my mind that Clone fans are not only ok with this, they are Jamie's biggest cheer leaders. It defines any and all logic.
