The Facts: Heading into training camp, we pondered which rookie runner would step up to push Montgomery for playing time. Williams was the easy guess. Through one week of practices, the fourth-round pick has already earned first-team reps. Veteran ESPN reporter Rob Demovsky notes that Williams has already "started to push" Montgomery. The rookie even took the first snaps of Thursday night's practice.

Diehards Line: We'll see about that. As NFL.com advised readers, we shouldn't make too much out of the running back rotation early in camp when tackling still isn't taking place, but the news is a good sign the coaching staff trusts Williams already. Williams entered the NFL out of BYU with the ability to hit the crease and is a capable receiver out of the backfield. What has set him apart at this stage, according to reporters, is his ability to pass protect -- something Montgomery is still working on as he makes the full transition from running back to receiver. Montgomery still seems likely to take the bulk of snaps when games matter, but Williams' progress will be something to keep an eye on during preseason games. If the rookie forces his way onto the field, the Packers' offense can become even more diverse.
