Well, all coaches are always going to talk up a team that they played, no matter what. Beating or losing to a team that is viewed as good/great always helps your own reputation.
That being said, I believe the rule is there to avoid some team coming in for one year, making a splash for cash, then reverting back to its former self, which probably wasn't good, and then leaving. I believe teams can leave D-I at any time, or stop their hoops programs at any time with no NCAA penalties (there could be conference or other agreements to address). When there were a lot more independents, it was potentially easier to game this system. But with the advent of almost every team being in a conference, then one would think the conferences would not let in a one-hit wonder, either. And now an independent probably couldn't get enough meaningful games anyway. So bottom line, I agree that it's time for the NCAA to revisit this rule.
