You're conflating a few of the objections here.
The home slate this year absolutely sucks, and replacing Coppin State with Howard doesn't make the home slate better for fans.
But replacing Coppin State with their MEAC counterpart Howard is potentially playing a school ranked over 100 slots better, which would really help our SOS.
Aside from the fact that those two games you noted didn't factor into the season tickets (so really didn't hurt the home slate for fans), they also didn't affect our SOS and so had no bearing on our seed line.
Atlantis, St. Bonaventure, and West Virginia are very good OOC games. It's a "Screw you" to fans that none are at home, but fine. But also, you don't need to replace UMES with Duke or Kansas (probably a bad idea to do that entirely). You do want to build a schedule that avoids this many of the worst 10-25 teams though. Unless these schools are better than we thought, it's going to bite us Selection Sunday.
