Review the season-ending RPI rankings for the last 10 years. Generate a list of which teams finished in the Top 50 the most times and rank them from most to least. You can weight more recent years more heavily if desired. Start a the top of the list, eliminating teams like Duke or Kansas that don't make sense for us to play too often, and schedule as many of those teams as you can. I didn't go through the exercise, but I'm sure those who do this for a living could and come up with a schedule that gives us a good number of opportunities to get Top 50 wins without being too ridiculous.
Alternatively, just don't bring back Coppin State.
