Albion's defeat by Oxford United on 28 February could well end up being one of the most important days in their season.
At the time, most thought it would be the day that signalled the beginning of the end for the Baggies' Championship survival hopes.
However, it appears that day might have been used as a line in the sand.
James Morrison said after the game: "When it gets tough, we don't get going."
That comment seems to have landed with many in the squad because "get going" is exactly what they have done since.
Albion are now four unbeaten since that dismal day (two draws and two wins), and ended a wait for an away win that stretched back to 1 October when they defeated Bristol City on Saturday.
It has been a remarkable revival for which head coach Morrison has been rightly credited.
But, while his leadership off the field has been integral, his captain's has been equally important on it.
Jed Wallace missed 16 league games through injury between late October and early January.
Albion lost a whopping 10 of those 16 games, yet few put the Baggies' poor form down to the absence of their skipper.
He returned with a bang after Ryan Mason was dismissed, scoring in the FA Cup for then interim boss Morrison before claiming a goal and an assist in Eric Ramsay's first game in charge.
Despite that impact, Ramsay only used Wallace sparingly across his eight league games with the Throstles' skipper averaging 41 minutes per match under the Welshman.
Morrison's appreciation for his captain appears much greater.
Wallace has started all but one of the five league games under Morrison so far, and he has embodied the new head coach's messages perfectly.
After the defeat at Kassam Stadium, Morrison demanded bravery, a stronger mentality and for experienced players to step up.
Wallace has not just heeded that call, he has set an example for others to follow.
No player in the Albion squad has recovered the ball more times, or won more ground duels, than Wallace over the past three games. Only midfield enforcer Ousmane Diakite has made more tackles in that period. Not bad for a right-winger!
But our captain has offered more than just tenacity and hard work – he has delivered quality and creativity too.
He has topped the charts for expected assists (xA) over the past three games, and only Isaac Price has created more chances than him.
Wallace turns 32 this week, but you wouldn't know it to watch him.
The way he flies around the pitch belies his age, and how he snaps at the heels of opposition players like a Yorkshire Terrier must make him a nightmare to play against.
His energy and enthusiasm appear to be rubbing off on his team-mates, who collectively made more tackles on Saturday than in any game for three months.
Former US president John Quincy Adams summed up the impact a true leader can have on a group better than I ever could, so I leave you with his immortal words.
"If your actions inspire others to dream more, learn more, do more and become more, you are a leader."
