Each week, I will ask for questions via Twitter with the hashtag #PackersMail. Feel free to submit yours at any point during the week.

@RobDemovsky #PackersMail Jayrone Elliott had an unbelievable series in St. Louis. Realistically, what can he do against first stringers?

Demovsky: Jayrone Elliott looked good from the beginning of training camp, but is he three-sacks-in-four-plays good? Of course not. But who is? I asked a scout who watched tape of the game if Elliott was that good or if Rams tackle Sean Hooey was that bad? The scout said: "Both." The Packers will want to see Elliott against better competition, and they still have two preseason games to do so. Keep an eye on No. 91 tonight against the Raiders and next week against the Chiefs and also note who he's going against, and then we'll have a better idea what to make of him. But he has certainly gotten everyone's attention.

#PackersMail do you expect to see Jeff Janis on the 53 man roster? If so will he get any playing time?

Demovsky: After what Jeff Janis put on film in St. Louis, there's no way the Packers can cut him and hope to slide him through to the practice squad. He'd get snatched up on waivers in a heartbeat. The one thing you can't teach is speed, and the rookie seventh-round pick has it. He's a lock for the roster after that 34-yard touchdown catch and run against the Rams.

@RobDemovsky What does Kevin Dorsey need to do to make the final roster? #PackersMail

Demovsky: He needs to hope the Packers have room for a sixth receiver. It's as simple as that. If the Packers keep six receivers, Kevin Dorsey will be the last one they keep. If they keep only five, Dorsey will be out. He has been showing up more often on the No. 1 special teams units, which also is a good sign. He could have helped himself by catching that ball along the sideline against the Rams, but it might come down to how many quarterbacks the Packers keep. If they keep three, then they might not be able to find room for a sixth receiver.

@RobDemovsky with quarless and Rodgers, and when Bostic comes back, that pretty much means J. Finley career is done in GB? #packersmail

Demovsky: I'm not sure one has anything to do with the other. If the Packers' doctors would clear Jermichael Finley to play football again following his neck injury, I think they would bring him back. But they haven't, so it's a moot point.

@RobDemovsky Thornton's impact minimal? 3rd round is high pick so he should be "good" yet haven't heard much about him. #PackersMail.

Demovsky: It's not unusual for a defensive lineman to be a little slower to make an impact. Look at Josh Boyd last season. He did next to nothing in training camp as a rookie last summer and barely got on the field the first half of the season. But by the end of the year, he was getting regular snaps and making an impact. The same could happen for Khyri Thornton. It's a big adjustment going against NFL offensive linemen. Give him some time.
