Tallis says the Broncos aren't too concerned about their form in the trial match, although he admitted losing the Roosters is a great disappointment considering they are among the competition favourites.
But what Tallis is concerned about is the refereeing of Tim Mander, who he claims was inconsistent throughout the game.
"There were three or four times when blokes were holding on too long, pushing or punching and nothing happened," Tallis said. "Then Stu (Kelly) is on his back and he gets sent to the bin. How can you hold someone down when you're on your back?"
"I've been playing the game for 20 years and I really have no idea. It amazes me sometimes what they give penalties for.
"Everyone is going to make mistakes. Referees are human, I can accept that. All we want is consistency."
The final penalty count coming out of the match was 11-5 in favour of the Roosters.
Tallis says the loss to last year's grand finalists isn't a huge concern, with the club's main priority being their round one clash with the New Zealand Warriors at Suncorp Stadium.
"We didn't get excited when we beat Melbourne last week and we won't stress about losing to the Roosters this time," Tallis said.
"Trials are about getting the processes for your season right and identifying where you need to sharpen up."
Today, Broncos officials announced plans to improve pre-match entertainment in an attempt to boost home crowd figures.
"Last season our crowds dropped a little, especially with the number of Saturday afternoon fixtures we got and with the time constraints we also faced our pre-game entertainment fell away," Operations Manager Brian McGrath said.
This year, he says there will be vast improvements.
�We will be having singers, bands, fireworks, prize giveaways, competitions and of course, our new cheer leaders will be performing,� he said.
Australian Idol singing sensation Paulini Curuenavuli will head the pre-game entertainment at Broncos round one clash with the Warriors next Sunday.
