WATCH: Kirk Cousins throws ugly pick-six

At a young age, we were taught life lessons. Always be kind to others. Make sure you protect your family. Always admit to mistakes. And more than anything, never throw the ball late to the outside.

Unfortunately, Washington Redskins quarterback Kirk Cousins missed this day in class.

And his team paid dearly for it.

Yes, that’s a 29-yard interception return for a touchdown for Philadelphia Eagles cornerback Leodis McKelvin. It also brought his team to within two points in this all-important NFC East matchup.

For Cousins, it’s one bad mistake in a season that’s seen him take the next step to star status. It also brought back bad memories of Cousins’ performance earlier in his career.
