Tom Coughlin is confident in Williams and Hillis, and has a plan for them heading into Philly.
"We expect him to be what he was a week ago, a downhill, north-south runner, which is what he does very, very well," Coughlin said of Williams.
The rookie running back had 65 yards on the ground, a touchdown and 18 yards through the air against Atlanta.
Hillis, who is also contributing on special teams, will be the power back and catch some passes, when needed.
"He’s done a nice job when called upon, his four-minute runs and powerful runs and also pass protection. Over the years he’s proven himself to be able to catch the ball out of the backfield, so we feel good about Peyton," Coughlin said.
Eagles coach Chip Kelly said his team won't focus specifically on Williams on defense, but will try to pressure him to possibly make mistakes.
"It’s never just about the running back, it’s about all five offensive linemen, the running back, the tight end and really Eli [Manning] and how does Eli handle it because it seems like he has the ability to make checks within the system that they brought with them," Kelly said. "You may think, ‘Hey, we’ve got a good one planned here,’ but Eli may get them in the right protection so that they can pick it up. We’re attacking their entire offensive protection, not just one guy."
This isn't a case of "next man up" for the Giants here. Jennings is a bonafide all-purpose back that can run, catch and block. Williams is a fine, physical, durable player but his receiving skills are still largely unproven at this level. Hillis is what he has always been: a short-yardage that can make plays in the passing game. Neither player gives the Giants the versatility Jennings does.
I see the Giants using Williams basically the same way they've been using him this season. I think Hillis will get more of the Jennings-type touches than Williams will on Sunday night. They could insert Michael Cox in some formations as well. Either way, there's no exact substitute for Jennings on the roster.
