Kirk Cousins awoke Monday to an avalanche of text messages and a vague sense that a greater weight than normal sat on his shoulders. The plays that hadn’t worked in Sunday’s 41-10 triumph over the Jacksonville Jaguars ran like a tape-loop in his head.

As it dawned on him that he’d awoken as starting quarterback of the Washington Redskins, Cousins decided that the best way to proceed was to change as little as possible about his routine. So he got dressed and headed to Redskins Park to review game-film with coaches and start studying for Sunday’s NFC East opener at Philadelphia.

“It’s important in order to have success in my situation to not treat things different and try to be as consistent week to week as possible,” said Cousins, 26, who stepped in for the injured Robert Griffin III in Sunday’s first quarter and engineered five touchdown drives in the rout. “If suddenly my preparation changes a lot or if I do something different, that is an indication that I probably wasn’t very prepared for the previous games.”

Cousins, Washington’s second-string quarterback until this week, has had mixed results in his past starts for the ailing Griffin. Last weekend’s performance was heroic; he completed 22 of 33 throws for 250 yards, two touchdowns and no interceptions.

With Griffin expected to miss at least eight weeks with a dislocated ankle, Cousins inherits the second-most scrutinized job in Washington for an extended stint. And he’s counting on past experience — the losses as well as victories — to serve him well.
