Brighton were unbeaten in 17 games in the 1987/1988 season in all competitions, when sneaking into the playoffs with the last kick of the game that season, still a club record.
Barry Lloyd had a couple of good seasons and a few bad seasons as Brighton manager over all if I remember correctly.
Apart from, as others have mentioned, it being the wrong finishing place. That run was ALL competitions, not just league.
