The NRL has a number of excellent head coaches, many that possess some of the best knowledge about the game of rugby league. This list ranks coaches based on their entire career but favours recent achievements more heavily.
Head coach of the Sea Eagles is Trent Barrett, who took over after the controversial sacking of club legend Geoff Toovey. Barrett managed to return the club to the finals in his first full season as coach, finishing in sixth position. The Manly coach has managed to stay competitive in 2018 despite losing a large number of players to serious injuries. Barrett will likely continue to improve as he gets more experience as a club coach.
