COLUMBUS, Ohio – It's already difficult to play Navy because of the tough, dedicated and disciplined players on any service academy's roster.

On top of that, No. 5 Ohio State must get ready for the Midshipmen's lethal, unique offense. Navy is one of the few full-time practitioners of the triple-option left at the college level.

So when the Buckeyes meet the Midshipmen on Saturday in Baltimore, they must prepare for a physical battle against a supremely conditioned team. They also must hone their knowledge of assignment defense against star quarterback Keenan Reynolds and Navy's other offensive threats.

The Buckeyes know they've got their hands full as they open their 125th season.
