The quiet gesture from Cassius Winston goes largely unnoticed amid the hysteria at the start of another Michigan State basketball game.

Just before tipoff, Winston greets his teammates at midcourt. Then he turns away, slaps his right hand toward the air in front of him, slides it near his left shoulder and leans forward, hopping into a shoulder bump.

The new pregame routine for Winston, the all-American point guard and team captain, isn’t to pump himself up. It’s a greeting he developed in high school, one he used almost daily. It is a handshake, and one of the many examples of how his habits — and the Spartans’ — have changed after the suicide of his brother Zachary in November.
