Hardwick doesn't fit the criteria of having played 50 games for Essendon this century and why are we including 2000? The 21st century started on Jan 1 2001.
The 21st century started Jan 1 2000. Any other logic is flawed. For example 1999 is the last year of the decade known as 90s. 2000 is the first year of the decade known as noughties which is part of the 21st century.
