On this Tuesday Buckeye Talk, Stephen Means, Nathan Baird and Andrew Gillis look back on Ohio State's 17-14 win over Notre Dame. Among the things discussed:

The high-level play of the secondary through four weeks;

How the defensive line held up against a quality Fighting Irish offensive line and a change in philosophy in how Larry Johnson rotates;

What to take from the low Pro Football Focus grades from the linebackers;

OSU’s defense was clearly the better unit the first four weeks of the season, but is there anything to still be worried about on that side of the ball?
