Former St Kilda great Nick Riewoldt has urged his old club to stick with Paddy McCartin despite his recent form woes.

The former pick one has struggled in the opening three rounds of the season, having only kicked one goal.

And while McCartin is not applying pressure on the opposition, the big man is somewhat of a liability to the team.

But St Kildaโ€™s beloved ex-skipper thinks McCartinโ€™s form can be attributed to his teamโ€™s poor play.

โ€œNot even Wayne Carey wouldโ€™ve got a kick in the forward line in the past two weeks,โ€™โ€™ Riewoldt told the Herald Sun.

โ€œThe Saints had 40 back-half turnovers against North Melbourne โ€” that is a world record.

โ€œPaddyโ€™s got a part to play in it, no doubt, but I donโ€™t think you get rid of him after two weeks, particularly with no Tim Membrey who is injured.

โ€œI think they have to keep playing him, absolutely.โ€

McCartin has copped the lionโ€™s share of criticism towards the Saintsโ€™ lacklustre 1-2 start to a season where many tipped them to be playing finals.

A type one diabetic, his match fitness has been questioned, including his ability to work up and down the ground effectively.

Saints coach Alan Richardson could not guarantee McCartin would line-up this weekend against Geelong.

A loss to the Cats this weekend would make it improbable that St Kilda features in this yearโ€™s finals. The round four clash takes place this Sunday at GMHBA Stadium at 4:40pm (AEST).
