It was a special day for the Klein family back in December as they gathered around their television to watch the New England Patriots play the Buffalo Bills on the road.
Sure, they got to see their local NFL team defeat a division rival, but the Kleins were most interested in what quarterback Mac Jones had written on his cleats as opposed to the ball being thrown from his hands.
Participating in the NFL's My Cause My Cleat initiative for the first time, the rookie was representing Boston Children's Hospital and Robbie – the Klein's seven-year-old son.
