Still, Payton said Monday the integration of the talented trio is, "a work in progress."
"It's something we think about a lot, too," Payton said. "If you separate Darren's role a little bit, if you start with some nickel packages and a little bit of this 'lighting' term we use where we're wanting him specifically on the field much like with Reggie. I don't want to say that's easy, but that becomes the easy part of the equation. So if we can establish that we have a package that involves Sproles both in the nickel and in the base, then I think the bigger trick is coming up with a ways between Pierre and Mark. We try to give them some semblance of a rhythm, too, maybe a couple of series at a time. That whole time there are some times and groupings that might trump whatever the rotation might be. But there's a lot of thought given to it. I don't know that there's an exact science to it because at the end of the week, typically, I'm going through (it) with (running backs Coach Bret Ingalls). I think more than anything they want to be able to see their involvement with the plan and each game kind of unfolds a little differently in regards to what you're in and what you want to be in. It's kind of a work in progress."
