Honest question: Mike Riley, underrated amongst the new hires? 2-2 vs Harbaugh w/a lesser OSU program (didn't have Luck nor the OL of Stanford, inferior resources, players) and gave Pete Caroll some TOUGH games vs loaded USC teams, including a win.
What Harbaugh has already done is completely united a huge fan base, rocked a basketball halftime show, and has Harbaugh throwback jerseys flying off the shelves.
