PATRICK Dangerfield has made a life-changing decision to move from Adelaide and join Geelong.

A (not so) serious conundrum facing the Cats' new superstar is the jumper number he will wear at Geelong in 2016, and he insists he still has no idea.

"It's not really a concern at this stage to be honest. I'm not sure what is available but I'm sure we'll get to that at some stage," Dangerfield said on Monday.

Dangerfield has worn two numbers in his AFL career. He was allocated the No.19 when he first joined the Crows as the club's first selection in the 2007 draft.

The following season Dangerfield moved into the No.32 guernsey made famous by Adelaide champion Mark Ricciuto.

Dangerfield wore the No.32 in 152 games for the Crows and made the number his own despite its obvious links with the 2003 Brownlow medallist.

But with speedster Steven Motlop entrenched in the No.32 at Geelong, Dangerfield is likely to have to search for a new number to continue his legacy in.

The No.9 appears to be the most appealing jumper number of those available, with the retiring James Kelly leaving the club after 273 games in the blue and white hoops.

Steve Johnson's No.20 is also up for grabs, with the three-time premiership Cat and 2007 Norm Smith medallist on the move after 253 games for the club.

Dangerfield, who hails from nearby Moggs Creek, wore No.35 during his junior career with the Geelong Falcons in the TAC Cup.

It just so happens that the No.35 has become available with young midfielder Jarrad Jansen seeking a trade to the Brisbane Lions.

The No.35 jumper is steeped in history having previously been worn by champion Cats Paul Chapman and Bill Goggin.

The other numbers available at Geelong are No.12 (Sam Blease), No.36 (Brad Hartman), No.17 (Hamish McIntosh), No.25 (Jared Rivers), No.27 (Mathew Stokes) and No.41 (James Toohey).

Something else to factor in is Geelong's loose system of allocating the club's first-round draft selection the number of the departed player (from the previous season) who played the most games for the club during their career.

However, as in previous years, the Cats' free agent selections and traded in players will have first choice when selecting their numbers.

Should Dangerfield wish to keep wearing the No.32 he could always sound Motlop out for a swap.

After all there is precedence, with Lance Franklin retaining the No.23 he wore for 162 of his 182 games with Hawthorn after Swans teammate Jordan Lockyer agreed to change jumper numbers to accommodate the superstar recruit in 2013.

However, Swan Ben Matthews refused to hand over Tony Lockett's famous No.4 jumper when he made a short-lived comeback to the game in 2002, after announcing his retirement in 1999.

However Motlop is a fan favourite at Geelong and it appears unlikely he would give up the No.32 without a good reason.

Dangerfield could look to the NFL where it is common practice for players who have an affinity with a certain jersey number to fork out thousands of dollars to swap with a teammate wearing their desired number.

Star cornerback Darrelle Revis paid former Tampa Bay Buccaneers teammate Mark Barron $50,000 for his trusty No.24 when he was traded from the New York Jets in 2013.

The move would be unprecedented in the AFL but which player would turn down $50,000?

No matter the jumper number Dangerfield wears next season, there is sure to be a big increase in membership sales at the Cattery in 2016.
