THE ATLANTIC 10 Conference has discussed the possibility of becoming a 21-team league for basketball, a source told ESPN.com Tuesday.

The extra teams likely would come from the Big East, should that conference continue to undergo changes.

The A-10 is a 16-team conference this season but Temple will be leaving for the Big East next year and Charlotte will be going to Conference USA.

Butler and VCU joined the Atlantic 10 this season.

The A-10's plan comes from the Big East's seven Catholic basketball schools, including Villanova, meeting with Big East commissioner Mike Aresco to discuss their options.
