It seemed so innocent late Saturday night, Matt Cullen, sounding like an old man well past his bedtime, talking about how he used to watch Jake Guentzel play high school hockey in Minnesota. But it said so much. Guentzel was 3 when Cullen broke into the NHL in 1997 with the Anaheim Mighty Ducks. The two are teammates now on a Penguins club that looks good enough to become the first repeat Stanley Cup champion in almost two decades. What makes their story so compelling is that each belongs. Each has earned his spot, Cullen at 40, absolutely an old man by his sport's harsh standards and the NHL's third-oldest player, and Guentzel at 22, a mere baby and the Penguins' youngest player. It's a beautiful thing, a wonderful dynamic that makes sports so much fun to watch.
