An eight-point loss to Wallaroos and a 16-all draw with Easts Magpies immediately spring to mind.
The newly-promoted A-grade club controlled large sections of both games, but poor handling, execution, and defence meant they are still on the hunt for their first win in the top grade for 15 years.
The third game Dreger included was last week's heavy loss to Wests Panthers.
While it was close at the halfway mark, the Panthers blew apart the Maryborough club's defence in the second half to win 40-16.
"Handling, effort - if we show how we can play then I'm sure we can win," Dreger said.
"We've put on points and looked good in patches, but we just need to put it together for the 80 minutes."
Dreger knew it would be a tough year when he stepped into the role as coach.
"It is highly unlikely we'll win the comp this year but the main aim is to keep building," Dreger said.
Maryborough Brothers will host The Waves Tigers at Eskdale Park on Saturday.
The Waves won their second game of the season in last week's 30-16 win over Easts, and have named a strong side.
Bustling prop Ikuna Manuofetoa, representative lock Chris Robinson-Ford and powerful centre Sekope Tua headline a powerful squad.
Tua tore through the competition last year to score 12 tries, an effort that included five in one game.
Dreger has swapped several players, with regular fullback Nic Golusin shifted to halfback and Anaru Nathan named at hooker.
"Nic probably doesn't have the build for halfback but it's his talk and leadership," Dreger said.
"Anaru's speed out of dummy half is pretty big for us.
"I just want the guys to get out and give it a good crack."
Kick-off is at 6pm.
