Phillip Adams was a journeyman NFL player whose career was cut short by injuries, a disappointment that apparently stuck with him during his post-football life.

The 32-year-old Adams fatally shot five people — including a doctor, his wife and their two grandchildren — before later killing himself, authorities in Rock Hill, South Carolina, said Thursday.

“He had an injury his rookie year,” Adams’ agent, Scott Casterline, told The Associated Press. “Some teams wrote him off and he had that stigma of a guy who was hurt. His ability was better than a guy who bounced around a lot.”
