As we count down for the start of college basketball season, we set out to put together a thorough guide for the sport’s non-conference season. The non-conference portion of college basketball teams’ schedules feature intriguing tournament brackets played in exotic locations and major U.S. cities, inter-conference showdowns with conference superiority at stake, and home-and-home series that take place in raucous on-campus environments.

These games can determine whether or not your team will make the NCAA tournament and what seed it gets if it does make the 68-team field. This list, of course, does not include every non-conference tournament, game or Division I school, but if you’re looking to find out what important early season games you need to watch, this is a pretty good place to start.

Here’s your A-to-Z guide for college basketball’s non-conference season.

AdvoCare Invitational

Dates: Nov. 22-25, 2018

Charleston Classic

The Charleston Classic’s field could be classified as sneaky good.
