Personally, I like HC in February with a big-name game during the thick of in-conference play. Do you really want to see a HC game against Howard, NJIT, or Maryland Eastern Shore? And during a moment in the season where there are fewer casual fans following the team? C'mon.
It doesn't really makes sense for it to be either (at the end of Fall semester, or in the spring), but one thing you DON'T want to do is chose a game where you're likely to get a large crowd anyway (vcu being a prime example of a game that draws outside of homecoming).
I'm sure you could do better than Howard, or UMES too if you do it during the OOC.
