SANFL great Graham Cornes has questioned Port Adelaide's decision to hand star midfielder Ollie Wines a new six-year deal, stating the 26-year-old is unlikely to see out the end of the contract.

Wines was already committed to the Power until the end of the 2022 season, with the new deal now keeping him at Alberton until 2026.

Speaking on FIVEaa, Cornes was flabbergasted by the news that Wines had penned a long-term deal with Port Adelaide.

“I’m puzzled with that,” he said. “A six-year contract, for heaven’s sake.”

“I’ll bet you right here and now he doesn’t see out the six years. That’s the way of football these days. This is no detraction on Ollie. I bet they don’t see the six years out with Port Adelaide.”

“He’s going to be subjected to all sorts of pressure. What are they thinking?”

Fellow presenter and two-time Adelaide premiership player Mark Bickley suggested there would be clear reasoning with the club's decision to extend Wines' contract.

“He’s going to be one of the higher paid players over the next two years… you’ve got some pressure – Rozee, Butters, Duursma – you want to lock those young players away. If you smooth it out over a period – and you have to make it attractive to Ollie – it seems to be the reason why they would do that," he said.

Carlton and Essendon have shown interest in attracting Wines to Victoria in the past several seasons.
