Billy Lange turns down D-League position

Villanova associate head coach Billy Lange has declined an offer to become the head coach of the Houston Rockets Developmental League affiliate, the Rio Grande Valley Vipers, a source told ESPN.com.

Lange is still considering a position with the Philadelphia 76ers, the source said.

Lange, who worked as Jay Wright's director of basketball operations from 2001-04, returned to the Villanova bench in 2011 after seven seasons as the head coach at Navy.
