cloke MAY be better than Tarrant.
Tarrant is an AA full back Collingwood did not have a KPP close to AA this year. Tarrant would easily be your best KPD and can play on both talls and smalls.
Tarrants only AA was in 2003 with the Pies as a Forward. In Tarrants best year a key back 2009 he didn't even get a nomination for AA, Presti did.
Presti is a far better stopper then Tarrant. Cloke kicked 5 on Tarrant and Jack Anthony kicked 4 on him in 2009, Tarrants best year.
Ben Reid and Nathan Brown are both 21. They did a great job all year in the premiership team and will only get better as 22 year olds.
Tarrant will be 30 with his best behind him. Tarrant will be best 22 but he wont play key back in front of either of these 2 guys let alone Presti if he plays on. Tarrant would need to fit into a back 6 that was the 2nd best defensive unit in the AFL. (2 points per game behind the best)
Tarrant is not a better forward now then either of Cloke nor Dawes and will definitely NOT play forward before either of these guys.
As I said, I'd happily trade Tarrant for pick 43 but to say Tarrant would be our best KPP at age 30 is reaching. He is not 28 anymore.
Scarlett is the best in the business. Have a look at him 2 years ago at age 28, compared to now aged 30. Still good yes, but not the superstar defender he was. More then likely the same thing will happen with Tarrant.
