Just how committed is the NFL to drug testing its players?

The league is so determined to keep its athletes honest that it will administer a random exam at practically any locale. As Washington Redskins backup quarterback Kirk Cousins recently found out, that includes a player's grandmother's town home.

So the league can test its players at any time, anywhere? At least they'll hold these guys accountable. But imagine the surprise on Cousins' grandmother's face when her grandson's visit was disturbed by a drug tester from the NFL.

For the sake of Redskins fans, let's hope this tweet means Cousins passed. The Michigan State product was a reliable backup for Robert Griffin III this year, and coach Mike Shanahan even deemed Cousins a "first-round talent."
