• The VFL introduced a new clearance system, "
10-year rule", in order to render the VFL immune from the sorts of "restraint of trade" difficulties that were being experienced, at the time, in New South Wales in relation to Rugby League footballers, whereby any VFL player who had played ten years with a single club was eligible for a free transfer to the club of his choice. • Although twenty-two VFL players were eligible to do so, only six players,
George Bisset (Footscray to Collingwood),
Barry Davis (Essendon to North Melbourne),
Carl Ditterich (St Kilda to Melbourne),
Adrian Gallagher (Carlton to Footscray),
John Rantall (South Melbourne to North Melbourne), and
Doug Wade (Geelong to North Melbourne) took advantage of the new rule. The rule was rescinded in May 1973. • The new
North Melbourne coach
Ron Barassi recruited champion half-backs
Barry Davis (who had already played 218 games for
Essendon),
John Rantall (who had already played 174 games for
South Melbourne), and champion full-forward
Doug Wade (who had already played 208 games for
Geelong). North Melbourne improved from last place in 1972 to sixth in 1973. • In Round 11
Kevin Murray played his 300th game for
Fitzroy. • In Round 21,
Hawthorn full-forward
Peter Hudson, who had been injured in Round 1 of
1972, returned to the VFL. He beat four opponents and kicked 8 goals. • In Round 22,
Hawthorn hosted its last senior
VFL football match at
Glenferrie Oval. The ground was notable for its temperamental playing surface and narrow flanks (wedged between the railway line on the one side and houses on the other). The venue had long been described by football fans as "the sardine can."
Hawthorn subsequently played its home games at
Princes Park for the next eighteen seasons. • The
Richmond Football Club won the premiership in all grades in 1973: its Senior Team, Reserves Team and Under-19 team all won their Grand Finals at the
Melbourne Cricket Ground on Grand Final Day; and the Essex Heights Football Club, which served as Richmond's Under-17 team, won the South-East Suburban League premiership. ==Awards==
