FOXBOROUGH, Mass. -- When the New England Patriots go through drills early in their practices, defensive linemen hear multiple voices, which is different from past years.
Energetic and intense position coach Brendan Daly is usually firing them up and drilling them on fundamentals.
Then there's the newcomer to the staff, former University of Arkansas head coach Bret Bielema. His presence is hard to miss, as he fits in well with the bigger-bodied tackles at the heart of the line of scrimmage.
And finally, there is Joe Kim, a martial-arts expert who was brought in as a consultant and is often seen focusing on hand placement and technique with the team's edge rushers.
