I wouldn't put the blame on Coach Landow. He has our guys very much physically fit and relatively healthy.
We are now in year 3 of his program, and I don't see any rash of injuries that could be attributed to his program.
The only S&C guy who I would say harmed ND's players was Paul Longo.
Part of the Longo fiasco was because of less than ideal methods (injuries in 2014 and 2016 were rampant), and the other part was because Longo was basically MIA during that 2014-2016 time period, due to health reasons of his own. During the times he actually did come to the office, I would guess that he wasn't thinking clearly.
He was relying on his less experienced assistants to carry out the S&C program, and those guys inexperience, combined with his methods, resulted in a lot of players going down with injuries.
If anything, that was one of the black marks that scared away the other two St. Brown brothers from coming to Notre Dame.
