FRISCO -- Friday's practice began like all Friday practices this season inside the Ford Center. Terrell McClain danced in front of the team during the stretching period. Fellow defensive lineman DeMarcus Lawrence joined him. As usual, Jason Garrett wore a big smile during the entire routine.Garrett has been impressed by how the group has practiced all season, so he doesn't mind when they have a little fun."One of the best things we do is come to practice and focus on what we need to do that particular day," Garrett said.
