BOSTON — It was an ordinary moment, but it meant everything to the father of a little boy with the rarest of diseases.
Last month, in the final seconds of a Sunday night football game, as Eagles defensive tackle Jordan Davis blocked a Los Angeles Rams field goal attempt to lock up a victory for Philadelphia, an exultant Kyle Muldoon lifted his 1-year-old son, KJ, in front of the TV in their living room. KJ, startled by the gesture, started to cry. As he apologized to the small child sporting an Eagles jersey Muldoon had bought him on the day he was born, he started to tear up too.
