We celebrate the (labor dispute-delayed) opening weekend of the National Lacrosse League's 2018-19 season – as well as the return of the iconic Philadelphia Wings franchise – with two of pro box lacrosse's most ardent fans and chief chroniclers.

Metro Philly natives Steve Holroyd and Dave Coleman are the engines behind the historical treasure trove known as RetroLax.com, which digs deep into the history of the pro indoor game in North America – and features a wealth of hard-to-find stories and rare game footage from circuits like the original six-team National Lacrosse League of 1974-75, the one-year National Lacrosse Association of 1968, and, of course, the precedents to today's NLL – 1987's Eagle Pro Box Lacrosse and 1988-97's Major Indoor Lacrosse League.

Holroyd and Coleman join host Tim Hanlon to discuss the origins of their interest in the game; their commitment to definitively "filling in" the surprisingly substantial and lengthy backstory of professional lacrosse in North America; what they've learned and who've they met along the way; and their thoughts on where the pro game is headed – as the NLL re-enters Philadelphia and expands into San Diego, and the outdoor Major League Lacrosse gets ready to battle the new Paul Rabil-founded, private equity-backed Premier Lacrosse League this coming spring.
