Each week, readers are invited to submit questions about the Green Bay Packers via Twitter using the hashtag #PackersMail. We'll continue that throughout the offseason. Here are some of the topics that came up this week:

@RobDemovsky any chance McCarthy gives up play calling next year? #packersmail

— Ian Stauffer (@StauffIt) January 30, 2015

Demovsky: Packers coach Mike McCarthy has been asked this before -- although not recently -- and his response is usually the same: If he felt like the team would be better served to have someone else call the offensive plays, then he would have no problem giving it up. He obviously hasn't reached that point. Now, there was something that came up indirectly about this matter in his season wrap-up press conference this week that was interesting. He was asked if he had any more information about why linebacker Clay Matthews wasn't on the field for a pair of fourth-quarter series and said, after mentioning Matthews had a knee injury, that: "As far as the doctors, especially being a play-caller, I don't get every play by play of what every guy was looked at during the course of the game. I really don't even get that until after a home game until I go back through the training room, and we have a list that we go through each guy he has seen. Just the way we're structured, unless it impacts the game as far as a player injury, I'm not really notified." Now, that's not to say McCarthy should or will give up play calling in order to be better informed of other aspects of the game. The point is that when the head coach is the play-caller, there are things that could slip through the cracks.

@RobDemovsky If the Packers recover the onside kick, does Slocum still have his job? #PackersMail

Demovsky: Well, they would probably be playing in Sunday's Super Bowl if they had recovered it, so I think it's safe to say he would. And then let's say they win the Super Bowl. How do you fire a coordinator? I can't recall a Super Bowl-winning team ever firing one of its coordinators, but perhaps it has happened at some point. Nevertheless, Shawn Slocum's fate was sealed when Brandon Bostick botched the onside kick recovery with just over two minutes remaining in the fourth quarter of the NFC Championship Game.

@RobDemovsky Is Richard Rodgers, bubba franks part deux? 6-9 TDs on 40-60 receptions per year? And a true red zone threat? #PackersMail

— B Z (@bzndallas) January 30, 2015

Demovsky: Bubba Franks was a massive target at 6-foot-6 and 265 pounds. He had 32 touchdown catches in his eight seasons with the Packers and although I don't have every one of them charted, it's a good bet that at least half of them -- if not more -- were less than 10 yards. I know several of them were 1- or 2-yard touchdowns. He made three Pro Bowls doing so. Richard Rodgers is two inches shorter and nearly 10 pounds lighter, so he's not exactly the same kind of target. However, he's probably more fluid as a runner than Franks was. That's why Rodgers has a chance to post a much higher yards-per-catch average than Franks, whose career average was just 9.0 yards per reception. Rodgers averaged 11.3 yards per catch as a rookie, and he has the ability to raise that number. However, he may never be the short-yardage, touchdown machine that Franks was in his prime, when he caught 27 touchdowns over a four-year stretch from 2001-04.

@RobDemovsky why did packers decline the sweezy personal foul? I'm going to ask until you answer me #packersmail

— Tom (@therealtkrings) January 28, 2015

Demovsky:: I spent time digging into this issue and here's what I found: For reasons that were never explained -- not even to McCarthy (I asked him on Wednesday) -- the officials said the penalty against the Seattle Seahawks' J.R. Sweezy was not a dead-ball foul. The way I understand the rule, that means that if the Packers accepted the penalty, it would have wiped out Clay Matthews' sack, which was a 15-yard loss for the Seahawks that made it second-and-30 from the Seattle 41. If they would have accepted the penalty, it would have been a 15-yard mark-off, but the Seahawks would have been allowed to replay the down, so it still would have been first down. Only if it had been ruled a dead-ball penalty would it have compounded the sack, so the question is why wasn't it a dead-ball infraction? I have no answer for that.

@RobDemovsky why doesn't it look like Clay Matthews enjoys playing football anymore? #PackersMail

Demovsky: I can't say that I've noticed that from Matthews. He looked like he was flying around like usual, celebrating with his teammates after big plays, etc. Now, was he totally thrilled with the move to inside linebacker at midseason? No, especially not at the start. He even admitted on Nov. 13 that "in a perfect world, I'd love to line up outside 100 percent of the time, get sacks, but we were able to do that from a different position. It worked out." As the season went on, it appeared that Matthews warmed up to the idea of splitting his snaps between inside and outside linebacker.
