In 2002, Jennings moved into the Giants radio booth with Bob Papa and the late Dick Lynch. He was also a part of the Giants pregame and postgame shows. Jennings was replaced in the booth by Carl Banks after the 2007 season and left broadcasting the following year.
"Dave was always a guy that I admired from afar, and when we had an opportunity to add him to the Giants' broadcast team — when John Mara brought him back to the Giants family — it was a treat to work with Dave," Papa said. "He was meticulous in his preparation, and Dave was a leader in rules interpretations. Dave knew all the rules. Whenever something came up, you could always turn to Dave and you knew he would get the rule correct and that was going to serve the audience best."
Jennings was part of the Giants' second Ring of Honor class in 2011. He joined the ring with running back Alex Webster, tight end Mark Bavaro and linebackers Brad Van Pelt and Banks.
Jennings didn't play football at Garden City High School on Long Island. Jennings attended St. Lawrence University, winning two letters in basketball and earning the punter's job as a walk-on.
Besides his sister, Jennings is survived by her husband, Harley. The family has asked that donations be made in Dave's memory to the Michael J. Fox Foundation (www.michaeljfox.org).
