The Cowboys haven't finalized their coaching staff, but another change was made when assistant strength and conditioning coach Walt Williams was told he will not return for the 2013 season.
Williams spent two seasons with the Cowboys.
The Cowboys had numerous hamstring injuries during the season and several players took extra stretching from head of strength and conditioning Mike Woicik and assistant strength and conditioning coach Brett Bech, along with Williams.
Players praised the work of all three men.
Williams would conduct the team stretching exercises before practices at Valley Ranch.
However, team owner/general manager Jerry Jones promised change within the organization and while he's released defensive coordinator Rob Ryan and running backs coach Skip Peete, he noted in a interview on Dallascowboys.com that he's taking an extensive look at the entire staff with coach Jason Garrett.
