Hubbs was well liked by his teammates, who included future Hall of Famers Billy Williams, Ernie Banks, Ron Santo and Lou Brock. Banks remembered, "Lots of young players do something special and you can't talk to them any more. Not Ken. One day, he got seven hits in a doubleheader. Pretty good for a rookie. But he didn't talk or act any differently than when he didn't get a hit." Hubbs was known for his faith. Reporters often noted that he did not smoke or drink alcohol, and that he attended church services while on the road with the team. With Hubbs's encouragement, Ron Santo quit smoking.
