Matt Breida is part of an impressive San Francisco 49ers running back group that ranks No. 2 in the NFL and is averaging 171.1 yards per game. His offense is No. 3 in scoring, and the 8-0 49ers might not have even reached their peak. Their best could be yet to come, which is a scary thought if you are an opposing team.

Beida joined the "RapSheet and Friends" podcast this week and discussed what could be on the horizon as the 49ers look to get some key starters, like Joe Staley, Mike McGlinchey, and Kyle Juszczyk, back. NFL Network's Ian Rapoport asked Breida if this team is going to get even better as the season continues.

"100 percent," Breida responded. "I feel like, each game, we're getting better. We still haven't played our best game yet, and every game, you can pick little things, little details that we can get better on. We still haven't played our best ball yet. I think we'll start playing our best ball toward the end of the year, and hopefully, we can carry that into the postseason."

Breida has 524 rushing yards on 99 carries (5.3 yards per carry) with a rushing touchdown and has added 14 receptions for 103 yards with a receiving touchdown. Running back Tevin Coleman has 355 rushing yards on 83 carries with five rushing touchdowns and one through the air while Raheem Mostert has 55 carries for 307 yards with rushing and receiving touchdowns (one each) himself.

Breida is credited with five starts this season. Coleman with three. The 49ers don't seem to have an RB1. They have an RB1A and an RB1B with RB2, Mostert, doing his fair share.

Breida isn't concerned with the label of "starter" and is more concerned with what is best for the team. It's a mentality that is present throughout the locker room.

"I think a lot of guys, especially at this level, they want it to be about themselves," Breida said. "But you see that the teams that are very successful and do great, it's not about you. It's about doing whatever role that you want to do, and it's a team sport. No one guy out there is going to win the game, or no one guy can go out there and win a Super Bowl.

"So I feel like that's what our team's done a great job (at), is buying it as a team. No matter who's out there, no matter if it's a backup or starter, we're all going to play the same way."
