ROXBURY TOWNSHIP - Twin girls from Morris County are now die-hard Seattle Seahawks fans after player Derrick Coleman answered a letter from them.

Sisters Riley and Erin Kovalcik have been hearing impaired since they were young, but haven't let that stop them from playing baseball, basketball or anything else. They recently saw a Duracell commercial featuring Super Bowl-bound Seahawk Derrick Coleman and felt an instant connection.

In the ad, Coleman says, "They told me it couldn't be done, but I've been deaf since I was three, so I didn't listen."

Riley decided to write him a letter, thanking him for being their hero.

Their dad tweeted a picture of the letter, which quickly got an amazing response. The twins say the team tweeted them back and referred to them as friends.

In his response, Coleman told the girls that even though they wear hearing aids, they can still accomplish their dreams, like he did.

"The guy's a hero, plain and simple," says father Jake Kovalcik. "He's not just a hero to my girls, but every kid out there who has struggled with something."

With their new NFL friend as an inspiration, Riley and Erin say there is nothing they wouldn't try.

Coleman invited the girls to throw the football with him if they're ever in Seattle.
