Oklahoma lost both starting cornerbacks, Dominique Franks and Brian Jackson, from last year's team. Their replacements, Jonathan Nelson and Jamell Fleming, played in spots last year -- and safety Jonathan Nelson played extensively at safety late in the season.
Utah State quarterback Diondre Borel is taking advantage of both. Borel beat Hurst for a 31-yard score to Xavier Martin that brought the Aggies to within 31-24 late in the third quarter, putting Oklahoma squarely back on upset watch.
On the Aggies' previous drive, Borel toasted Nelson for a 42-yard strike to Dontel Watkins. You figured there would be some early struggles for Oklahoma's secondary, even though it returns both safeties from last year's team.
Few figured those struggles would be this bad. If the big plays don't stop, Oklahoma might be in trouble.
