This list looks pretty detailed. It looks like there are openings available. Coaches for Cancer is open and usually attracts good teams. As for challenges the Big East, A10, MWC, and P12 are not involved in any challenges.
I didn't see East Carolina, Houston, or UCF on the list for any of the events or games.
* Temple is in the Puerto Rico Tip-off with some pretty good teams(Butler, Utah, etc.).
* Tulsa is in the Paradise Jam with a fair list of teams.
* UCONN is in the Battle 4 Atlantis with some good teams (Gonzaga, Texas, etc.). ** UCONN also play in the Jimmy V Classic against Maryland
* Cincy is in the Barclays Classic with decent teams.
* SMU is in the Las Veagas classic with fair team.
* USF plays Kentucky in HOF Events #1 (Round Robin)
* Memphis plays OSU in HOF Event #2 (Round Robin)
