Butler's depth has proven too much for most opponents. The team's reserves have outscored the opposition in 18 of 21 games, including all nine Big East games.
The No. 11 Bulldogs (18-3, 7-2 Big East), who have won seven of their last eight games, play host to Georgetown (11-10, 2-6) at 8 p.m. on Saturday at Hinkle Fieldhouse in Indianapolis.
"Everyone that comes in is a good player and everyone produces," Georgetown coach John Thompson III said.
Butler coach Chris Holtmann said his starting lineup and rotation can fluctuate from game to game.
"Some of it is matchups and what we've seen on film," Holtmann said.
