Prolific St George Illawarra winger Brett Morris says the memory of watching tapes of his dad score in a losing grand final has quelled any concerns he may have had over his NRL finals' drought.

Morris, the Dragons' main source of tries over their dominant regular season with 20 four-pointers from 22 games, is yet to cross the line during the finals series with the side's potent left edge kept in check to date.

It's a drought the Test winger is unaccustomed to having gone try-less in back-to-back games only once this year, and in an ominous sign for Sunday's grand final opponents Sydney Roosters, Morris has not gone three straight games without a try since becoming a first grade regular in 2008.

But while Morris would love nothing more than to cross the stripe at ANZ Stadium on Sunday, he said he would happily be kept quiet if it meant taking part in a victory lap.

Morris said he remembers his dad Steve `Slippery' Morris scoring for St George in the 7-6 grand final loss to Canterbury in 1985.

"I'm sure he'd give anything back to win that game and not score that try," Brett said.

"He tried to make us not watch it but we're very proud of what dad did and being a little kid you're always pulling out the tapes and having a look at them.

"I think that's one of his biggest regrets that 85 grand final."

Brett said his dad would definitely be in the crowd on Sunday, as would brother Josh - the Bulldogs winger the first to ring Brett the morning of the preliminary final win over Wests Tigers on Saturday to offer his support.

Brett said the Dragons would work hard on the training paddock in a bid to rediscover the spark that made their left edge the most ruthless in the competition, but was adamant the side had enough other options to put a winning score on the board.

"Yeah they've (the tries) dried up, but who cares, we're winning," Morris said.

"I'd rather a win than score a try and I'm sure all the other boys are the same.

"You put the team before yourself and what you want to achieve because we're a family here."

The secret to Morris' drought may be a simple as a change in footwear, after he revealed he had left his favourite pair of boots back in Wollongong for the clash against the Tigers.

Meanwhile, the Dragons are set to adopt the same team-building approach they took heading into the clash against the Tigers with the squad to set up camp in Sydney ahead of Thursday's grand final breakfast.
