Griffith will look to continue their upward trend when they make the long trip to take on Tumut on Saturday afternoon.
The Blacks picked up a crucial win over CSU Reddies before the representative bye last weekend and will be looking to carry that form into their clash with the Bulls.
Morriss knows it won't be an easy task for the Blacks as they set off on their three hours and 16 minutes road trip.
"Tumut is always a tough side to face, especially over there," he said.
"They need to keep winning just like we do. We can't afford to come away with anything other than a victory, and it's going to be tough given it is our longest trip of the season."
The Bulls are sitting in fourth position after the first seven rounds of the season but are only inside the top four by one point with Albury snapping at their heels.
Over the representative break, Chris Latu was selected in the Brumbies Provincial team after strong performances for Southern Inland and Morriss will be hoping he carries that form into the weekend.
"Hopefully Chris will be available this weekend depending on work commitments," he said.
"Having Sai Ahomana back made a big difference in the last game as well, and a few of the other boys are starting to find form as well, which is good.
"The club is on an upward trend, and we want to keep that moving forward."
It will be a simple game plan for the Blacks according to Morriss as they look to pick up their third win of the season.
"We will just be going with the basics to make sure we aren't missing our tackles and holding onto the ball," he said.
"It's a work in progress with these boys, but it is starting to come through, and hopefully they can show it on the weekend.
"We can't afford to give Tumut too much ball because they have some big bodies who can run over the top of us if given a chance."
