What happened: Adam Kilgore traced funds from former NFL players into a Ponzi operation run by a man now dead. The trail raises questions about former Arizona Cardinals executive Steve Keim's dealings connected to that money.

Why it matters: Keim previously ran Arizona's front office, placing a former decision-maker beside players' financial losses. Cases built on broken trust inside football circles tend to draw legal and league scrutiny beyond the field.

What to watch: Watch for responses from Keim and any follow-up from authorities or the league.
