Even in a shutout victory in London on Sunday, when you'd expect Peterson to help salt away the win, the running back saw just six snaps and four carries (for four yards).
Despite Peterson currently collecting dust on the sideline, running backs coach Joel Thomas told Herbie Teope of The New Orleans Times-Picayune the 32-year-old runner will get his chance eventually.
"It's just a matter of time," Thomas said. "I really feel like this block, it's going to break.
"We just have to keep on chipping and you keep grinding, keep getting after something and ultimately something positive is going to come out of this."
Thomas pointed to game-flow as the reason Peterson has been tethered to the bench. Kamara, for instance, was targeted heavily in Sunday's win, catching 10 passes for 71 yards and a score.
"Immediately all of sudden AK is getting open," Thomas said. "So, boom, we flip the switch, got off that and you see a guy that's hitting, converting on first downs, five targets, completions, all this stuff."
"There's some wiggle there as far as that goes, but unfortunately like the last game there's a couple of series in there that AD is starting off and going, and we're three-and-out."
Part of those three-and-outs are a product of the inefficiency of Peterson's carries.
While Peterson has yet to cause much of a public ruckus about his role, it's worth wondering if he'll continue to bite his tongue if he remains stuck on the sideline.
"He's been a professional about it," Thomas said. "I mean, go to high school, go to college, go to pros: When was the last time he was kind of second fiddle in an offense?
"He comes down, he practices hard, and he asks the questions in meetings. When he needs to be corrected, he takes it, he rolls with it and I have nothing but respect for the man. Regardless what he's done in the past, it's what he's been doing here."
