It is the only class thing to do. USC should release every kid who asks them to do so. USC can then re-pitch them and try to get them to re-sign with full knowlege of the recently announced NCAA penalties. The kids also could reopen discussions with any other teams they choose. Of course, we all know this is not going to happen because USC is not a class program. But it should.
So, what should Henderson and any other kid who wants out do? They should get together and tell USC that either USC does the above (at least with respect to them) or they are going to hire an attorney and sue USC for fraud. I guarantee USC's coaches and assistant coaches heavily downplayed the NCAA investigation and likely penalties. These kids relied on what USC told them. USC told them the violations were minor and the penalties would be a slap on the wrist. Since USC had received the NCAA's notice of alleged violations prior to signing day (and I highly doubt it shared that notice with these kids), USC induced the kids to sign their LOI's based on material misrepresentations of the facts. That is fraud, and a contract based on fraud is voidable by a court of law.
More importantly, I do not think USC would like to have a public fight and lawsuit with its highest ranking 2010 recruits. All of USC's files, records and emails would be accessible via the discovery process and all of USC's coaches and assistant coaches (including coaches who have recently left such as Pete Carroll) and all of the kids USC spoke with during the recruiting process about this issue could be deposed under oath. That would be an absolute nightmare scenario for USC. USC will release these kids from their LOI's if forced to under that type of pressure.
Note: I posted this once before, but it was buried in another thread and I am hoping that someone on this board will know one of USC's recruits and forward it. I do not. These guys are getting f%cked and someone needs to help them figure out how to make USC back down.
