The 2020-21 campaign delivered a devastating, chaotic end for Grimsby Town as The Mariners finished a crushing 24th in League Two, resulting in relegation to the National League after a five-season stay in the EFL. The season was defined by severe turbulence, including Ian Holloway's mid-season resignation before the return of fan-favorite Paul Hurst, whose efforts ultimately failed to arrest the slide. Amidst the struggles, veteran forward Lenell John-Lewis battled to anchor the club's anemic attack, netting four goals in a season built on on-pitch anxiety and a profound struggle for form. It was an unforgettable, dark year that saw the historic club fall out of the Football League, cementing a painful, defining chapter in the club's modern history.
