Rebecca Kill was at the wheel, husband Jerry was in the passenger's seat, and they were driving from New Jersey to their home in Illinois lake country a few days before Christmas in 2017.
Jerry had resigned after one season as Rutgers offensive coordinator. Once again, he had a challenging season with his epilepsy, this time triggered to some degree when he was run over on the sideline in the second game of the season.
There was no sadness in his voice during a lengthy cell phone conversation that day. He had flown to Illinois a couple of days earlier to meet the Kills' new grandchild, Emery Ann, and he was excited to see the baby again as a reward at the end of the long drive.
Emery Ann will turn 4 this month and Friday, again on a cell call, Kill said: "She's a beautiful little girl and she loves her 'Pa Pa,' I can tell you that.''
Then, Kill paused and said: "She's a little confused, though. Emery said to me, 'Why are you a Aggie, Pa Pa? You're a Horned Frog.' "
Jerry Kill has been a variety of items since he stopped being a Gopher on Oct. 28, 2015: a Wildcat, a Scarlet Knight, a Saluki, a Hokie and, most recently, a Horned Frog.
And now, there's a segment of the college football world aiming the same question at Kill as did his granddaughter:
Why are you an Aggie?
