FRISCO, Texas — The Cowboys began practice Tuesday with the well-known refrain.
They’ll recite it as they warm up Wednesday, too, and on Thursday amid pregame stretches before facing the Raiders.
“As Markus would say,” a member of the strength and conditioning staff will exclaim, “sum-of-deez!”
Cue the cross-body, horizontal arm swings that former Cowboys strength and conditioning coordinator Markus Paul believed were necessary even as their formal descriptor eluded him.
