Hawthorn great Jordan Lewis has suggested former teammate Isaac Smith would benefit a move to Carlton in the upcoming free agency period.

The Blues' finals hopes were crushed on Sunday after a 16-point loss to cellar-dwellers Adelaide ended their chances of a top eight finish.

Speaking on SEN, Lewis looked to be a match-maker for Smith and Calrton, suggesting the move would work well for both parties.

“They’ve got talent and they just need to show improvement,” he said.

“They need to add maybe a few players to their list, you think of someone like (Hawthorn's) Isaac Smith who has that outside run would suit them really nicely.

“But I do think there’s been improvement (this year at Carlton).”

The Blues have given up 30 unanswered points in 17 of David Teague's 27 games in charge, with Lewis starting their must overcome the ongoing issue to become a great side.

“Where they fall away (in games) is situation stuff,” he said.

“Good sides, and when you have the ability to train during the year, can train situations that may pop up in the game. They haven’t had time to do that (because of COVID training restrictions), they have a young list and a new coach who would want to put his players in positions that they might find themselves in games.

“It’s hard and been a very difficult year to practice that but you rely on your leaders (like) Patrick Cripps to will your side over the line but when you give up a lead like they did against Adelaide, it’s just too much to pull back in a shortened game.”

The Blues sit at 7-9 after their penultimate game as they look ahead to their clash with Brisbane in round 18.
