Carlton’s quantity of tall forwards has come under the microscope as the 2020 trade week edges closer.

Some believe it would be in the club’s best interest to let one of their big men go, particularly if it meant gaining a star back such as Sydney’s Tom Papley.

But Footy Classified panellist Kane Cornes has voiced his reluctance for the Blues to go down that path, given the that trading a young star such as Harry McKay or Charlie Curnow may come back to haunt the club.

“A few of these players have some currency. It’s just which ones Carlton want to keep. They are too tall forward of the ball,” he said on the Channel 9 program.

Levi Casboult is above 30 years of age so not much currency there, you keep him as a soldier. Mitch McGovern, no-one is going to match the contract he is on at Carlton so unfortunately as much as he has underdelivered, he is going to have to stay.

“The other three do have currency, particularly Charlie Curnow, but I wouldn’t be trading any of these guys. They are three that could come back to bite you.

“I wouldn’t be giving up Charlie Curnow. He is one player who could come back to bite you.”

However, fellow Footy Classified panellist Matthew Lloyd said that Harry McKay may be the key for the Blues gaining another star midfielder.

“McKay would be the one if something came up. Carlton won’t do it, but to get someone like Josh Kelly through the door it would be a Harry McKay,” he added.
