"Jerome is an abrasive player," Byrne added.
"When he left here in 2011 he was probably one of the best in the world at being that abrasive player. I'm just looking forward to him settling in and getting comfortable in our system.
"Once he gets clarity he can go at 100 miles an hour."
The Blues' malfunctioning set piece has been a concern this season — the 67 per cent scrum success and 79 per cent lineout success among the lowest in the competition, but Byrne said he was happy with how his side was progressing. He believed improvements were being made every week but conceded the Blues were taking time to adjust to the new scrum engagement calls.
And although Luatua was far and away the most used lineout catcher (22 takes, the next best is lock Tom Donnelly with 11), Byrne said he was comfortable with the 22-year-old's workload in this area.
Byrne pointed to Brumbies loose forward Ben Mowen (28 takes) as an example.
"There's reasons why it happens. Locks must catch the ball but when you've got loose forwards as good as Ben Mowen or Steven, then you use them."
In their two losses to the Bulls and Lions in South Africa, the Blues appeared a little passive in contact at times. Luatua and Saili, two direct runners, improved their team's performance in this area against the Cheetahs, with Byrne saying that go-forward had been a big focus.
"When we're getting good gain line, we're getting good quick ball. The two go hand in hand so we've been working on that."
