Xavier and Dayton should play. They don't NEED to play, but there is more to gain from it than not. It would be fun for the fans, it would create an intense environment for the players prior to conference play starting, and it would be a quality match-up.
There is something else I didn't think about that Joe Lunardi, of all people, brought up. There is almost nothing that fits this category. Non conference rivalry between two tournament regulars that are not FBS schools. Xavier v Dayton would certainly fall into that category. He didn't point that out as pointedly as that in the link below, but I know he has made that point before. Out of everything on the list, it was the game that most caught his attention, and it was because of that reason.
I also now think that the reason XU and UD don't play isn't the reason that most people think that it is. The coaches are friends and would simply rather not play each other. I know that isn't what the internet message board world thinks, but that is what I've heard from people whom I think would know. So, I've decided to just leave it at that, I guess. But, **** it would be fun to see it come back.
