McCarthy: 'Still working through' backup QB rotation

Green Bay Packers coach Mike McCarthy spoke with the media for about 12 minutes on Tuesday morning. It was his last media session before Thursday's preseason finale against the Kansas City Chiefs at Lambeau Field. Here are the highlights.

On whether guard Josh Sitton could move to center:

Josh Sitton has always worked as a center in our rotation. Once again, you don't ever go into a game or offseason just trying to train one player. If you watch our quarterback exchange on a daily basis, we'll work up to five centers. Josh is a great player. I have the utmost faith in him.

On his comfort with DuJuan Harris as a kickoff returner:

I think DuJuan has done a good job. Obviously, he needs to handle the ball cleaner all the time. He's getting a lot of time at the jugs, so I like the improved work ethic there. I think he has a chance to be impactful once he gets going.

On the backup quarterbacks' playing time in Thursday's game:

Quarterback rotation-wise, we're still kind of working through it. Biggest thing is I think Matt (Flynn) has played behind Scott (Tolzien), so we're trying to balance that out.

On whether the quarterbacks could go series by series:

I'm not a fan of that. You have to give the QB a chance to create momentum and flow. You have to be smart about that.

On undrafted rookie linebacker Jayrone Elliott's preseason:

I think it's a great example of a young man getting an opportunity. Obviously, three sacks in six plays doesn't happen every day. It shows his ability. He's gotten a chance here. He played as much as he's ever played against Oakland. He'll play more than he ever has against Kansas City, both special teams and defense.

On wide receiver Jarrett Boykin:

It's clear he's taken the next step. I love the way he plays. He's physical. I think he's exceptional at the top of his route. His ability, you see the strength and balance to separate from the defensive backs. I think he's had an exceptional camp.

On the importance of special teams ability when filling out the roster:

You want as many 4-down players as possible. Obviously, the definition of a 4-down player is someone who plays offense or defense in the first three downs and then special teams on the fourth down. So, l yeah, it's important. It's definitely a big factor.

On the potential number of quarterbacks kept on the roster:

Matt and Scott aren't just competing against each other. You have to keep your best players. They're really competing against the other positions, and that's what it comes down to.

On whether past performance plays a role in roster selection:

Your past experience is par tof every individual's value. I think that's like anything in life. I don't think that's going to be a determining factor. Every individual that's competing for a roster spot is building their value, and we have to weight hat. Sometimes you don't pick the 53 most talented players or the 53 most productive players. You're charting a path to the Super Bowl.
