There is a real possibility those two might earn a break before the end of the season, too.
Corey is a 29-year-old veteran who has played 226 games while Varcoe was recovering from shoulder surgery for much of the pre-season.
Although their form is good, it is a long year for midfielders, particularly with the new substitute rule.
The most recent premiership team to take the field on Grand Final day without at least one player in the line-up having played every game was Essendon in 1984, a team known for its versatility under Kevin Sheedy.
The Bombers were full of running too when it mattered, kicking 9.6 (54) in the last quarter to overrun the Hawks, turning a three-quarter time deficit of 23 points into a 24-point victory. Geelong appears to have been heading down this path of player management since it lost the 2008 Grand Final to Hawthorn, after it won all but one game leading into the decider.
That year, the Cats had six players in the Grand Final side who played every game (five played every game in 2007). In 2009, that figure was reduced to two - Joel Selwood and Corey Enright - and last season no player on the Cats' list played every game.
Whether or not it was planning or circumstances that led to this outcome, there is no doubt the Cats had learned their lesson about peaking at the right time well before Chris Scott arrived as coach.
Geelong has used only 33 players this season, three fewer than Carlton, Fremantle and Melbourne, but four more than another premiership contender Collingwood.
The Hawks have also used 33 players while the Eagles have had just 32 players run out.
It is the quality of the 33 players the Cats have used (or maybe it is the quality of the system those players have slotted into) that is the envy of most clubs.
Many of the Cats' seven changes for last Sunday's game - with Fremantle's seven the same weekend the equal-highest for the season - were forced, with Jimmy Bartel, James Kelly and Darren Milburn injured and Josh Hunt and Mathew Stokes suspended.
Brad Ottens and Nathan Vardy were suffering general soreness and the opportunity to rest them was taken. Having players fresh and available at the business end of the season in late September and
early October is the priority. That is the luxury winning close games provides.
As the season develops, team changes are becoming more frequent, with last week's total of 54 by the 16 teams the highest for the season.
The average number of changes a game is increasing as the season takes its toll (and clubs turn to young players), with the early-season average a game just below four steadily increasing to 6.75 a game.
It's no wonder Cats president Colin Carter suggested a month ago that a premiership medal should be awarded to all players on the club's list.
He knows every player on the list matters when it comes to qualifying in good enough shape to be fit and firing in finals.
