A lot of thought went through my head being reminded of this tragic loss:
1) What Joe Delaney could have been. The guy was only a few years into his career when he died trying to save these kids. Overcame his father's objections about him playing the sport to become a standout All American at a AA school, raising his stock to a second round pick. Then he went on to become a dynamo -- Pro Bowler, AFC RoY, set 4 Chiefs franchise records and helped them to their first winning season in almost a decade. His next season was shortened by strike and a detached retina injury, then he passed the next year.
2) We need more people like Joe Delaney in this day and age. Delaney was just that kind of guy -- he paid for the funeral of one of his teachers when he learned they couldn't afford it. The kind of guy who would rush into water to save kids when he himself couldn't swim.
3) Learning to swim is a life lesson that everyone should learn. The water the kids were in was only six feet deep. Maybe Joe thought he could handle that, but as an ex-competitive swimmer and lifeguard, you should never underestimate a body of water and even the most experienced swimmers can be drowned trying to save a drowning/panicked person. You can drown in just a thimbleful of water, let alone with a person clutching on to you in a life-or-death situation where they aren't thinking straight. I ardently believe everyone should learn how to swim -- it's a life skill, like reading, that should be taught right away to toddlers, getting them comfortable in the water, learning to float, and basic swimming. Like driving, it's a tool every adult should have.
