it's sportsmanlike to a team who hasn't barely won anything. The giants are hungry and they need all the points they can possibly get. It's up to the Redskins to stop it if they don't like it.
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
