Interesting but not workable for ND with no JUCOs and rare transfers accepted.
The 25 is not adequate to replenish a base of 100 considering attrition to injury, academics, "I miss my girl friend", etc.
Former Tennessee head coach Johnny Majors was new at Pittsburgh in '73 and was the prime reason for the NCAA setting recruiting limits. He brought in about 100 freshman on scholarship with the prior approval of the school administration. Summer practices were tryouts as he separated the chaff from the wheat. Every position was contested. The practices and workouts were brutal. Quit or get cut and you were off scholarship.
PITT bought themselves a title in '76 on the backs of the 100 plus the legs of a RB named Dorsett who was one of the 100.
Majors made 10 in home visits to Dorsett's house. PITT ***'t coach Jackie Sherrill average 3 vists a week for 6 months to see Dorsett. Sherrill's mother baked Dorsett's favorite pie whenever Dorsett visited campus.
All of the above are NCAA violations today. The NCAA recruiting regs are extensive because coaches like Majors, Bryant, and Saban are constantly trying to circumvent them to get an edge.
Back to increasing the 85 to 100.
All the smaller schools/programs would fight this. The additional 15 players and the equipment, support staff, recruiting expense etc would add about a $1 million a year to their budgets. Most programs don't make money from football and for them the red ink would increase. At some that barely make a profit, non-revenue sports like LAX would take the hit. The Alabama's, Michigan's, etc would welcome the escalation in the Arms (and legs) Race. Outspend the competition!
program changing recruit and they did the right thing. It's not nearly the "contract" people think it is... 9/10 if you ask out of your LOI for a legitimate reason the school says OK.
