I don't think this is even arguable. ND struggled to recruit and develop OL from 1996 (when Davie fired Joe Moore) until Hiestand's arrival. Suddenly we're recruiting the position as well as any team in the country, it looks like one of the team's strengths on the field, and advanced stats like ALY bear that out as well. Then Heistand leaves, and our ALY drops off a cliff. Maybe a coincidence, but I'll remain skeptical until Quinn shows he can develop our top-shelf talent and our OL returns to being one of our perennial strengths.
LOL! It's inarguable because its become a Notre Dame fan truism. But any statistic that shows Toledo's OL as #5 and ND's as #105 in a year ND made the playoffs is a skewed. AND IT IS ADMITTEDLY A DIFFERENT METRIC IN 2018!!!!
In 2012, without HH, we got to the ND at 189 ypg. Not exactly a disaster.
Martin, Watt, Cave, Golic, Lombard. Ed W. had trouble recruiting because ND was coming off the Weis years. He was getting ship turned around, and did a good job with what he had. He did pretty good recruiting to OSU.
HH was a great coach, and did a great job teaching excellent form. While he was here we had mixed results in the run game, for various reasons, many outside of his control. But that is kind of the point. Too much blame, too much praise.
It seemed to me, until the last few years, HH's reputation was a "pro" coach that could really get the most out of the ELITE talent, but didn't pay a ton of attention to the other guys. Over his tenure, he kept Martin and Watt on track, and fine-tuned them for the NFL. Developed Stanley, N. Martin, and McGlinchy very, very nicely, and got front row seats to the Q Nelson experience, which was likely inevitable. No one else is very notable, IMO.
If you go back and look his recruiting was a mixed bag. Great some years, bad other years, and fine some other years. Some of his fine years too, were saved by improbable late commitments like Banks.
In term of rushing ypg, the statistic I prefer, the HH years started slow, looked promising in 2015, seemed to regress in 2016, then amazing 2017 happened and cemented the HH legend:
2013: 151 (#80) Martin, Watt, Hegarty, Elmer, Stanley (better line, worse results)--
Why? overall team talent issues.
2014: 159 (68) Stanley, Hegarty, Martin, Lombard, Elmer (worse line, same results)
2015: 207 (28) Stanley, Nelson, Martin, Elmer, McGlinchy (much better talent, but huge talent boom on offense with Kizer, Fuller, and Procise)
2016: 163 (80) (McGlinchy, Nelson, Mustipher, Kraemer, Bars) offensive skill position issues hurt, but defensive nonsense kills team.
2017: 269 (7) (McGlinchy, Nelson, Mustipher, Kraemer, Bars) - veteran line, great RBs, and a defense
2018: 182 (51) This would have been 3rd best in the HH era. I chalk it up to Chip Long's approach. The line had struggles, but every line does (2017 - UGA and Miami).
So I think he is a great coach, but I think he is getting too much credit for havin McGlinchy and Nelson coming back for that extra year.
