If you read the article some of your questions/comments would have been answered.
The COACHES voted Wednesday. The vote that counts is the President's vote on Friday. Similar to the NCAA where coachs vote in committee but the Presidents cast the NCAA Member vote.
The 28+28+28+28 doesn't amount to more than 85 on the team but of attrition or because they don't renew scholarships (year by year basis per NCAA) for some upperclassmen.
It does give them leeway over over schools when a current player transfers after the Spring Game or is academically ineligible after the Spring Semester. At ND such a loss usually means a walk-on gets lucky for a year and gets a ride. At Bama they just add one of the kids from their "waiting" er, grayshirt, list.
If the COACHES voted Wednesday, then my point still stands. Mustchamp and Richt have both, publically, came out and made comments about how they disagreed with oversigning. It's just another sign of the hypocrisy of the SEC if true.
Schools should, during a signing period, be able to sign no more than a total of 90 scholarship players. That's it. Just having the ability to sign 100 total over a 4 year period will pretty much lead to what is happening now, the "JUCO" farm system, Medical Hardships being exploited, un-renewed scholarships, ect. There is an inherent risk when recruiting. If you take that 5-star with the questionable grades because you think he can help your pass rush, then you're accepting that risk that he might not qualify, or some type of attrition will occur. You should not be able to dial up the Minor Leagues and get someone else.
If it wasn't so late, I'd go into a rant about the B.S. of schools being able to, pretty much without penalty (actually, they are rewarded for it if they practice in oversigning) file the paper work to not renew a scholarship. In a system where a student-athelete has to jump through hoops to transfer (get a release, be able to transfer to a school of their choosing and not denied by the head coach, sit out a year, ect), a coach shouldn't be rewarded for removing him from the team.
