Former Port Adelaide midfielder Kane Cornes believes Carlton's future may not be as bright as many people think.

Following the Blues' 30-point loss to the Swans at the SCG on Friday night, Carlton moved to 1-10 on the season, and have a percentage of just 63.5%, the worst in the competition.

Players like Charlie Curnow and Patrick Cripps do excite Cornes, but it's the next crop of youngsters he's unsure about. 

โ€œI donโ€™t want to continually knock Carlton, but have we overestimated the strength of their young talent coming through?โ€ Cornes told SENโ€™s Crunch Time on Saturday morning.

โ€œI look at the players who played last night, the genuine A-graders, we know about Charlie Curnow and we know about Patrick Cripps.

โ€œThen Iโ€™m not as convinced on the next level, I think Sam Petrevksi-Seton will get there and heโ€™ll be a 200 game player.

โ€œAfter that, Jacob Weitering Iโ€™ve got a question mark next to him although I think heโ€™ll probably make it, Jack Silvagni showed signs as you said, but a question mark once again, Harry McKayโ€™s a question mark, he wasnโ€™t in the side last night.

โ€œPaddy Dow we think is going to be a good player and you canโ€™t judge him too harshly in his first year.โ€

Cornes went on to say he's been more impressed with Brisbane so far this season, and would choose the Lions' list over Carlton's at the moment.

โ€œIf you look at their side compared to Brisbane, I think Brisbane has got more talent coming through the ranks with the players coming through,โ€ he said.

โ€œIโ€™m still not as optimistic as the Carlton supporters are.

โ€œRight now Iโ€™d rather be Brisbane than Carlton, call me a little bit cynical but Iโ€™m not quite convinced.โ€
