Former Richmond and GWS player Brett Deledio has agreed with Kane Cornes that Patrick Cripps could leave Carlton for greater success if the losses keep coming.

Earlier this week, Cornes said Cripps was within his rights to leave Carlton before his contract expires at the end of 2021 if the Blue do not improve.

Deledio left Richmond in search of greater premiership success at the Giants. He would not blame Cripps if he went searching elsewhere.

"He's had all the individual honours already, at what point does he [consider leaving] if he doesn't see it over the next few years? I kind of agree a little bit with Kane," Deledio told foxfooty.com.au.

"If that's what motivates him [premiership success], wherever he goes he's gonna get very well paid because he's an absolute star.

"The hardest thing is you can think you're going to a place to get success but it doesn't always work out that way and I'm probably front and centre in that."

Deledio believes the crucial role Cripps plays for the Blues could amplify the toll of constant losses.

"He must feel the weight of having to perform every single week for them to try and get over the line," Deledio said.

"Most of the time when they've won, it's off the back of him absolutely dominating. That's a huge weight to carry, that's an extra four or five kilos every week to his already massive frame. It would just weigh you down.

"To be honest, if it does continue I think you ultimately just see careers cut short because of it because you think 'There's gotta be more to life than this', and once you have kids you start to realise what's important in life."

The 33-year-old, two-time All Australian admits that you can never quite predict when premiership success would come.

"I don't think you can predict where it is and there's a huge amount of luck that goes into everything, everything's gotta go right to win a premiership," Deledio said.

"I've never won one, I tried to predict it but I didn't read the tea leaves.
