In 2000, Johnson was a part of the Bulldogs side that ended Essendon's winning streak of 20 games in the classic round 21 clash.
Right on half-time Essendon player John Barnes turfed Johnson and left him concussed.
At the end of the game Johnson ran on the field and confronted Barnes, giving him the last word.
It is considered to be the greatest mark of all time by many, including in a 2021 AFL-run poll of more than 30,000 fans, where Moorcroft won with 25% of the vote.
In 2005, he kicked a Goal of the Year contender – an amazing soccer-style half volley from an extremely tight angle on the boundary line.
He started the 2008 season against the Adelaide Crows in his 300th game and kicked five second-half goals, including three in the last seven minutes as the Bulldogs came out on top by three points.
Their remarkable season came to an end when they lost to a strong Geelong side in the Preliminary Final by just under five goals.
In his later seasons, Johnson twice had the misfortune of missing shots on goal after the final siren to win the game.
A year later in the same round, Johnson had the same opportunity but this time against the Geelong Cats from 10 metres in front of goal on a tight angle in which he also missed.
In 2010, whilst recovering from a previous injury Johnson, was struck by the club's drinks cart in training.
