Ryan Day and staff
Ohio state will not only have a talented roster, but also a very talented staff. Day is one of the best young coaches in the game and has been regarded as offensive genius.
You have to think Larry Johnson will still be around, getting more of his D-Lineman NFL ready, and Brian Hartline will still be on staff after the receiving core had a great year under the new coach. Day will also likely bring in more help for a lackluster Buckeye defense, as they look for a revival on that side of the ball in the offseason.
Talent plus coaching is always an equation for special things.
