If USC appeals and only delays the penalties (which would be my guess), USC would be even less appealing for Andre Yruretagoyena, since he would be there for 2 post season bans instead of 1. In addition, Nick Perry would be in play due to the relaxed transfer rules under the penalty.
My take is that they should not appeal. Trying to operate under a cloud is usually a mistake, something RR could relate to.
I'm sure if he could do it over, RR would have paid the buyout and moved on. Perhaps the media vultures would not have been circling the campus looking for carcasses.
