The statement said the ADs and coaches are specifically concerned with three of the changes.
The first would allow schools to hire additional staff, beyond the allowable 10 full-time coaches, that would focus solely on recruiting. The second would deregulate phone calls and text messages, allowing coaches to contact a prospect an unlimited number of time beginning July 1 after the prospect's sophomore year of high school.
The third would allow schools to send an unlimited number of mailings to prospects.
The Big Ten athletic directors and coaches did not raise concerns with the removal of restrictions on how many coaches can recruit off campus at one time or the elimination of required materials a school must send to recruits, such as lists of banned drugs and the school's Academic Progress Rate data.
Meyer said the people who came up with the idea to deregulate recruiting probably had never gone through the recruiting process as an athlete or coach.
"I'm not a big fan of deregulation," Meyer said. "I'm a big fan of firm, harsh penalties for people who break rules, not saying, 'Just go — we can't follow all this stuff, so have at it.' I don't agree with that at all."
Pelini said the NCAA rules makers need to meet with football coaches and administrators to develop a good understanding of the challenges in recruiting. Pelini said the easing of the rules will cause recruited athletes to spend less time concentrating on their schoolwork and developing as an athlete and person.
"The more time a kid is spending on the phone texting and on the telephone and doing all the other things that are taking away from that is doing the kids ... a disservice."
Pelini said he would grudgingly change the way Nebraska recruits if the rule changes are implemented July 1.
"You're going to have to change some things in your staff and how you go about things to give yourself the best opportunity to keep up with the Joneses," Pelini said. "Believe me, we'll do what's necessary to put together the best classes we possibly can."
