The top-ranked team in the country will host #5 Notre Dame in a high-noon showdown in the Shoe. This is the first top-five match-up of the 2015 season between users, and the winner immediately vaults itself into pole position for the Rose division title. Here's what to watch for. When Ohio State has the ball... The Buckeyes are not just #1 in the country. They also boast the top ranked offense and defense in the NCAA based on points and yardage per game. The Buckeyes offense has largely been a benefactor of great starting field position this season, whether it be through quick stops by the defense or the dynamic return game of Braxton Miller, Curtis Samuel and Dontre Wilson. In this tilt, the Buckeyes will likely face their worst starting field position of the season, and will do so against what is countably the stingiest defense its faced all season. Quarterback Cardale Jones has been efficient and consistent, but largely untested. Will he be able to challenge one of the best secondaries in the country? The Buckeyes will need Michael Thomas, the team's leading receiver, to create separation on the outside and keep Notre Dame's defense honest, as the Domers will most likely focus on stopping the Buckeye's ground game first, and with good reason. Ohio State has the most devastating rushing attack in the country. The most difficult part of defending Ohio State on the ground is the fact that they can come from every angle. Yes, Ezekiel Elliot is the workhorse Heisman contender, who totes the rock 20+ times per game. But the Buckeyes also mix in sweeps and counters to their H-backs - a scatback/slot receiver combo - and Jalin Marshall, Dontre Wilson, Curtis Samuel and Braxton Miller all have the speed and agility to take it to the house on any play. Defending the Buckeyes is truly a pick-your-poison task this season, and it will be interesting to see what vial Notre Dame chooses to drink from. Ohio State can excel with the power running game, lateral running game, intermediate passing game and of course the deep ball. You can key in on one, two and maybe even three aspects of their offense, but you truly cannot stop it all. When Notre Dame has the ball... The Silver Bullet defense will get its best opportunity of the season to truly prove that the great defenses of Ohio State's past have new company with this year's unit. So far the only time teams have really scored on Ohio State has been when its backups are on the field, and even then the Buckeyes have maintained the #1 scoring defense in the country. Safety Vonn Bell is a ball hawk, and that could spell trouble for the Irish. Quarterback Malik Zaire has been a bit of a trainwreck this season in protecting the ball, throwing 10 picks through five games against only 4 touchdown passes. Now he's asked to come to the Shoe and not hold onto the ball? It's a tall order for the sophomore quarterback. The silver lining for Notre Dame is that they have one of the best offensive lines in the nation. Yes, Ohio State's defensive line is just as - if not more - impressive. But if anyone is to stifle the pass rush of Joey Bosa and Adolphus Washington, it's definitely Notre Dame. The Irish prefer to play up-tempo, but that could play in Ohio State's favor. If the Buckeyes can force quick punts, its going to put a ton of pressure on Notre Dame's defense. Perhaps the Irish will try to slow things down a bit in Columbus this afternoon. Overall the Irish's best bet to win this game is to maintain great field position with long drives, and score touchdowns in the red zone. jandy cyhiphopp jandy cyfan13 Rhight KnightNoles Antonio T.
