Stephenson burst onto the scene in his rookie year in 2018, booting 38 goals in Collingwood’s grand final campaign to claim the Rising Star Award.
He fell out of favour of Nathan Buckley’s side this year and looked devoid of confidence – kicking 14 goals from as many games.
Speaking on AFL Trade Radio, Barrett believes Stephenson is also on the trade table.
“There is a lot going on behind the scenes regarding Jaidyn Stephenson,” he said.
“He’s got a long-term contract to the Pies, certainly for two or three more years, but the Pies are also open to him not being part of their mix from next season onwards.
“It’s now official there is all sorts of stuff going on behind the season, they won a final, beat West Coast, went out, finished top six, but clearly what’s been going on has been something that will be one of the headlines of the 2020 trade period.
“The Jaidyn Stephenson one has come to light in the last 24 hours, we know there’s been issues off the field, he also went in 2020 with a glandular fever ailment, but it wasn’t a great year for him … this is a man who put together one of the great first seasons of footy in 2018.
“As I said a few moments ago I can tell you that the Pies, the default position is he’s a contracted player, but I can tell you the Pies are open to moving him out as well as part of what they do in 2020.”
