Sports science plays a role in monitoring Kam Chancellor

Schlereth believes Seahawks beat Bears 100-0 (0:58)

On NFL Live OT, Mark Schlereth and Jerome Bettis break down the Sunday afternoon matchup between the Chicago Bears and Seattle Seahawks. (0:58)

Here are three things to know about the Seattle Seahawks' Week 3 matchup against the Chicago Bears.

1. Pete Carroll explained Friday that the Seahawks can use specific data to evaluate where Kam Chancellor is from a physical perspective. Like other teams in the NFL, they have players wear GPS trackers during practice. Because Chancellor is entering his fifth NFL season, the Seahawks have plenty of existing data (speed, heart rate, etc.) on him. That has helped them determine where he is now compared to previous years.

"We do a lot of stuff to monitor our guys' workload, and the accumulation of information is what really gives us good accuracy and ability to predict what’s up," Carroll said. "Since he’s only been here a week, we don’t have a lot to go on, but we can compare to stuff we’ve had from last year and all that. So that’s what we do. We do a very in-depth analysis of our guys and how they’re taking to the work, and we operate with that information and adjust accordingly.

"We've been working really solidly with it for a couple years now. Interesting that you would bring it up today. I just did mention that we have enough information now that we can really start to predict stuff. You have to have a backlog and a reservoir of stuff, and as we’ve stuck with it, it’s seemingly coming to the surface a lot. We’re talking about it quite a bit because we think the information is really accurate."

Chancellor is expected to play Sunday, but the Seahawks will monitor his workload. The data they have accumulated over the years will help them devise a precise plan.

2. Michael Bennett will line up against his brother, Bears tight end Martellus Bennett, this weekend. Playing on opposite sides is not something they look forward to.

"It’s one of those things where you don’t want him to make plays, but you kind of want him to have good plays every once in awhile," Michael Bennett said. "And you really don’t want to hit him hard. I’m like, 'Damn, Kam. You came back this week?' It’s just crazy because you want to see him have some success, but not against you."

Added Martellus Bennett: "Honestly, I don’t look forward to playing against Michael. We’ve never been two of those brothers that are super competitive against each other. We’ve always been on the same team. So I kind of dread lining up against him, but it’s just one of those things that we have to do. I’m not ramping it up like, 'Oh, I’m going to kick your ass' or 'You’re going to kick my ass.' It’s more like I’m just always hoping my brother plays well and just hope for the best for him and the same thing. I’m pretty sure we’re going to end up lining up against each other a couple times, so it’s going to be kind of weird, because it’s never been our thing."

3. Seahawks offensive coordinator Darrell Bevell was asked this week why the team runs so much out of shotgun.

"It’s what we do our zone-read out of," Bevell said. "It incorporates where there’s usually four elements that are going on in that same play that helps us be successful."

This is the foundation of the Seahawks' offense. Wilson has to decide whether to keep the ball, hand it off or throw it to the perimeter. Chris Brown of Grantland has written about these packaged plays extensively, and they are an integral part of Seattle's offense.
