Center Brandon Davies, small forward Tyler Haws and point guard Matt Carlino are in for certain Friday when the team plays Tennessee State.
But how about those other two spots? That, and rotation in general, is a work in progress.
"We need to really evaluate the matchups and then kind of go through our best scenario," Rose said.
He's been doing this long enough, and successfully enough, that Rose knows it could take some time to figure out the power forward and shooting guard roles. Nate Austin and Josh Sharp at the former, Brock Zylstra and Craig Cusick at the perimeter spot, have split up minutes.
And the question remains this particular season if the minutes could be dished out by matchups (especially at the defensive end), hot hands or if the eighth-year head coach can have players solve the battles through their play, and allow him to find starting-five consistency that sticks, aside from health issues.
Rose continues to praise the added level of depth that this year's team has, even after losing its best scorer (Noah Hartsock) and top perimeter defender (Charles Abouo) to graduation. The Cougars are no strangers to losing a top scorer, as only Jimmer Fredette returned from his junior to senior season to break that particular string.
That should be Davies' role this year, especially as he has continued to refine his outside shooting, and continues to hit 3-pointers in practices as he did in a couple of exhibition games.
"That's definitely something he's improved on," said Haws, who returned from an LDS mission and also played with Davies when both were freshmen.
As a whole, Rose is concerned about the bevy of new players "understanding our system" and what the team does at both ends of the floor.
This isn't 1-on-1 basketball anymore, like some offseason practice. New guys may have talent to excel at that level, but Rose won't have that as the top priority. They must know how to play with the older players.
"If you can figure that out, and fit in with the other group of guys, that's really going to increase your chances of playing," he said.
Pace of play and consistency continue to be two big talking points.
Rose expressed after last weekend's exhibition-game win that there were hovering "agendas" that needed to be snuffed out.
BYU held a lofty advantage on second-chance points against Division II member Findlay. But Rose is not naive. He knew some of that boiled down to the obvious talent and size advantages the Cougars held.
He wanted to see better first-chance scoring, which didn't happen until later in the game.
Now starts the fun part: Scores count.
Rose has more playing-time experience this year than he did starting last season, even with all of the fresh faces that are on this roster. Carlino took his lumps as a freshman. Zylstra had ups and downs in his first season of extended playing time. Haws and Davies are expected to provide the individual consistency that must exist for BYU to reach its goals.
The "agenda" comment was rare for Rose, however, to express such a concern publicly.
"We've addressed it. Hopefully our guys will understand that the success of our program is we all play with one agenda, and that's to win," he said.
∫Anson back: Sophomore guard Anson Winder practiced the last three days. He missed the first 19 sessions and two exhibition games because of an ankle injury suffered at the beginning of the school year. Rose said the team is "bringing him back slowly."
Winder started 15 games last year and played in 34.
∫Kaufusi comment: Media continue to ask BYU's head football and basketball coaches about Bronson Kaufusi. The defensive lineman has expressed interest in playing some basketball when the football season officially ends after the Dec. 20 bowl game. Bronco Mendenhall doesn’t sound too enthusiastic right now.
Rose is...well, not optimistic at this point, either.
"We'll see," Rose said, giving a small laugh when the topic was brought up. "That's a long ways down the road...if it happens."
∫Great scout team: BYU had some extra help preparing for its first game. Former standouts Lee Cummard and Trent Plaisted are both in the area as their professional seasons ended, and they had "scout team" duties running Tennessee State's offense Wednesday. Also, BYU women's soccer coach Jennifer Rockwood watched part of practice.
