"Ronnie has been a friend of mine for more than 50 years and is like a brother to me," Banks said. "On the field, Ronnie was one of the greatest competitors I've ever seen. Off the field, he was as generous as anyone you would want to know. His work for diabetes research seemed unparalleled. Ronnie was always there for you, and through his struggles, he was always upbeat, positive and caring. I learned a lot about what it means to be a caring, decent human being from Ron Santo."
