Ohio State plays an easier schedule than ND nearly every season. Their SOS is almost always a joke.
Notre Dame is no longer the standard, however, they are still firmly rooted in the upper echelon (top 15-20 teams) in terms of their facilities (when the upgrades are complete) and ability to recruit. Therefore, if the talent is retained and developed (two factors that have been an issue in South Bend of late) Notre Dame will be in that conversation with Alabama, Ohio State, USC, Michigan, Florida State, Clemson, Florida, Georgia, Oklahoma, Texas and whatever other schools are going through upswings in the various conferences.
Three things that Notre Dame must do in the next 5 years to firmly entrench itself in that group.
1. They must hire an elite recruiter post Kelly and that coach must focus on talent development. He has to be an energetic guy that the kids are enamored with.
2. They must beat Stanford on a regular basis. ND cannot afford to lose 3-4, 4 and 5 star recruits to Stanford each year. That's a back breaker when you're recruiting from a pool that is more shallow than most.
3. Strength and conditioning must always be cutting edge. They can't ever fall behind again. That was crippling.
