What happened: Dallas Cowboys defensive coordinator Christian Parker spent individual practice time coaching rookie defender Caleb Downs on man-coverage technique, per Ed Werder. The hands-on session pairs the coordinator directly with his top defensive draft investment during regular-season preparation.

Why it matters: Dallas has leaned on its rookie class to anchor a reworked secondary as the Cowboys defense seeks consistency following Parker's coordinator debut. The franchise also recently added veteran coaching support to the defensive staff and committed to buying ahead of the Nov. 10 trade deadline.

What to watch: Downs' man-coverage reps and defensive role will be tested in the Cowboys' upcoming Sunday home game.
