The Blacks are one of only two teams to beat Waratahs this season, the other being Wagga City in round one, but head into their elimination final clash off the back of a 31-29 loss against Leeton on Saturday.
However the coach wasn't displeased with their efforts against the team who finished the season in sixth.
In fact Morriss took the blame for the two-point loss.
Twice he turned down penalties from close range in the last five minutes, believing the Blacks were further behind than what they actually were.
"Basically it was a fundamental mistake by me for not checking on the score," Morriss said.
"With five or 10 minutes to go the scoreboard stopped working, didn't update and we were only two points behind when I thought we were four.
"I indicated to take the tap when they were asking to take the kick on two occasions 10 metres out, directly in front and it would have sealed the game.
"It's probably cost us the win but I'm really happy with the momentum of our defence as the tries Leeton did score were 50-metre runaway tries off luck from the bounce of the ball and a couple of really bad misses from a young fella we had up.
"Overall I was really happy."
Griffith can't afford another slip up when they face Albury at Conolly Rugby Complex on Saturday.
The winner will take on the loser of the major semi-final between Waratahs and Ag College while the loser has to look ahead to season 2020.
However the Blacks have plenty of injury concerns.
While Chris Latu returned, and scored a double, in the loss to the Phantoms, Saione Ahomana is still a couple of weeks away with a hamstring complaint.
Dan McGreal and Jack Glyde are also in double for the clash while prop Blake Theunissen is waiting on scans on a rib injury sustained on Saturday.
Griffith scored a 31-24 win when the team's last met, but Morriss is looking for more consistency after needing a late rally to take the win on the Border.
"We seem to start well but it is middle of our game that has a bit of a hole in it," he said.
"We will have to work hard on it this week.
"There will be nothing in this game again, they are a quality team and had been on a roll up until last weekend."
The Blacks also have plenty of incentive with the chance to play in a preliminary final on their home job.
The last time Griffith host a Southern Inland final was in 2016, when the Blacks didn't have a presence in the first grade fixture.
