Holtz's famous bitch was that he couldn't get players into ND that beat him when we played OSU in the 90s. There is a bit of a unproven myth that Admissions got tougher during The Holtz era. It was probably more of a fact that Holtz continued to push the Admissions envelope and Admissions pushed back and drew a line.....depending on who you talked to some thought it was about time. At this point it is more folklore than anything else.
