Wondering about a player, a past game or another issue involving the Bears? Senior writer Larry Mayer answers a variety of questions from fans on ChicagoBears.com.

Interesting to see the Bears opening against the Rams. How did they fare over the years against Matthew Stafford when he played for the Lions?

The Bears are 9-11 all-time against Matthew Stafford, who has completed 63.6 percent of his passes for 5,440 yards with 32 touchdowns, 23 interceptions and an 86.3 passer rating against them. That's actually fewer TDs and more interceptions than Stafford has in the same number of games versus the Green Bay Packers (37 and 20, respectively). He also has a better career passer rating against both the Packers (89.9) and the Minnesota Vikings (89.5) than he does versus the Bears.

Having quarterbacks in veteran Andy Dalton and rookie Justin Fields with two vastly different skill sets, are the Bears going to teach two completely different offenses or just change a few plays here and there?

The Bears had some experience with that last season when they played both Nick Foles, a traditional pocket passer, and Mitchell Trubisky, who possessed more mobility. Pass game coordinator/quarterbacks coach John DeFilippo was asked about that Wednesday during a Zoom session with the media, and here's what he said about game-planning for Andy Dalton and Justin Fields: "This is not the first time that a lot of us in this organization have had a quarterback that's had a unique skillset in terms of being able to run the football. When you get down to it, the nuts and bolts of your game plan, if you're going from one guy to another, there's really only 10 or 12 concepts or ideas that are really different from what you're going to do from one guy to the next. But it's not like we're going to line up and run triple option wishbone with Justin Fields and not with Andy Dalton. The core of your offense stays the same, because there are 10 other guys on offense as well. You just may tailor it here and there to what that quarterback does well. That's a good question because I think people have the tendency to think you have two call sheets, and that's not the case."

I was very happy with the signing of free-agent running back Damien Williams, a Super Bowl winner with the Chiefs. Do you expect him to share carries with David Montgomery in the Bears backfield?

Veteran running back Damien Williams was definitely an excellent pickup during the offseason; he'll bring depth, talent and experience to the Bears backfield. But I would expect David Montgomery to remain the primary ballcarrier. Here's what first-year running backs coach Michael Pitre said about that topic Wednesday during a Zoom session with reporters: "David is obviously our starter and our bell cow, but Damien is going to come in and what he said from Day 1 is that he wants to come in and compete, and I think that's the mindset that all those guys have in that room. They want to come in and compete and bring their best to the room and to this organization and just help us win football games."
