Everyone and his dog are still piling on the OSU secondary but I believe they are light years improved from last year's crew. Exhibit 1 would be the improved coverage of various flash screens that Cincy threw at them. Last season the vast majority of those play would have gone for first downs and then some.
I put those three bombs on the coaching staff, not having any deep help when they knew Cincy had a quality home run threat. Finally Urban made the adjustment at halftime, directing the defense to play a looser coverage and keep everything in front of them.
I don't see anything back there that isn't fixable.
