Lions Mailbag: Is this the year Matthew Stafford puts it all together?

The Detroit Lions veterans report to training camp Sunday morning and while Jim Caldwell is slated to talk later today, camp will officially open Monday with a 3:30 p.m. practice at the team's headquarters.

In advance of that, we'll once again try to answer your questions below. To ask a question for a future mailbag, use the hashtag #LionsMailbag on Twitter, email me at michael.rothstein@espn.com or ask away on my Facebook page.

Now, on to your questions.

@mikerothstein: Ryan Broyles has a decent chance to make the roster as long as he remains healthy. After Calvin Johnson and Golden Tate, receiving snaps and spots are pretty wide open. Corey Fuller has an inside track on one of those spots, in part because he's one of the few tall, outside receivers with any experience the Lions have in camp. But for those two or three other spots, anything can happen. Broyles is in a contract year, so he would have to outperform Jeremy Ross, TJ Jones, Lance Moore and Andrew Peacock to make sure he has a spot instead of feeling somewhat safe about one because of the team's prior draft pick investment in him. But he's healthy and not coming off an injury the prior season for the first time in his professional career -- so it will be his best shot to really make something happen.

@mikerothstein: An extension for DeAndre Levy is definitely possible soon as the Lions would like to keep him in Detroit. There wasn't really a ton of saved cap for Detroit off Ndamukong Suh leaving because the team traded for Haloti Ngata before the start of free agency. So a lot of those "saved cap dollars" went there. The potential benefit for Detroit in the long term will be in the team's ability to secure more defensive pieces for the future. The Lions have potential contracts coming up for Levy, Tahir Whitehead, Darius Slay and Ezekiel Ansah on defense and Larry Warford down the road a small bit on offense. Those players are the future of the Lions so making sure they all remain Lions will be key. That's the benefit of not signing Suh -- not cap savings in 2015.

@mikerothstein: Matthew Stafford did that in 2011. He threw for 5,038 yards, 41 touchdowns and only 16 interceptions while leading Detroit to a playoff berth. The main difference there is Stafford had little choice but to throw the ball all the time because Detroit had one of the worst run games in the league. The difference this season is the Lions are hoping they have enough of a run game to have some semblance of balance on offense. That would open things up for Stafford, Calvin Johnson and Tate while taking some pressure off the offensive line. As I wrote last month, that hasn't really happened often in Detroit since 2001, but that explains the reasoning behind how Detroit drafted in 2015. But to answer your question, this is the best chance Stafford has to have that combination of massive stats and winning.

@mikerothstein: Not sure who that player ends up being because George Johnson was still pretty under the radar when camp started last year. On the defensive line, Phillip Hunt and Corey Wootton would be guys I'd look at. Wootton has more experience and Hunt showed some potential a few years ago in the CFL. Taylor Mays could be another guy who surprises -- not in winning a starting job at safety but possibly forcing Detroit to take five safeties or beating out Don Carey for the No. 4 safety job. Those would be the players I'd focus on.

Jorge from Facebook asks: Will Special Teams become consistently 'special'?  Aside from a new coach, what changes can we expect in Special Teams becoming significant game changers?

Rothstein: The Lions are hoping that happens this year. The kicker and punter -- Matt Prater and Sam Martin -- are pretty much set and have the chance to be among the top players at their positions in the league. The biggest question is at returner, where Jeremy Ross is the incumbent with very little job security. He's been pushed by rookie Ameer Abdullah and a gaggle of veterans with and without recent returning experience. Tough to say how impactful that unit will be until the returner position is solved.
