Only seven losses in five-plus years. That’s the backdrop for coach Urban Meyer at Ohio State University. The 62 victories in Columbus — including a national championship following the 2014 season — have cemented Meyer’s no-doubt status as a College Football Hall of Famer. But you know what really illustrates his success? It’s the seven defeats suffered by his Buckeyes. They are so rare, fans know them by heart. None in 2012, of course. The 2013 clubbing by Michigan State in the Big Ten Conference Championship Game. The stunning 2014 loss against Virginia Tech. The home defeat against Michigan State in 2015 that prevented an unbeaten record. The didn’t-see-it-coming 2016 shocker at Penn State. A pair of bowl-game losses against Clemson, including last season’s 31-0 Fiesta Bowl defeat in the national semifinals. And now, Saturday night’s 31-16 bubble-bursting loss against the Oklahoma Sooners. “This is not the first time we’ve had a tough loss,’’ Meyer said in Monday’s post-mortem, which predictably focused on what went wrong against Oklahoma instead of looking ahead to stopping Army’s wishbone offense. “Fortunately, (we) haven’t had too many. “But the ‘B word’ doesn’t come out. We’re not blaming anybody.’’ Inevitably, though, the focus will shift to two people.
