The Detroit Lions finished up one of its most successful seasons -- record-wise -- in franchise history. Now, the offseason begins with the combine, free agency and the NFL draft.

To start that process, we’ll look at each position group over the next two weeks, analyzing what worked, what didn’t, and project what could happen between now and training camp.

The series begins today with quarterbacks.

2015 Free Agents: Dan Orlovsky; Kellen Moore (restricted)

The good: Matthew Stafford didn’t get injured this season. Let’s start there, and considering the importance of the quarterback spot, that’s a big thing. Despite entering his seventh year in the league, he doesn't turn 27 until Feb. 7. Stafford was instructed to do three things this season: Get his completion percentage up. Keep his turnovers down. Win games. He did all three, completing 60.3 percent of his passes, throwing only 12 interceptions and winning 11 games. At least three of those wins -- New Orleans, Atlanta and Miami -- came from his leading the Lions on game-winning drives late. He also threw for more than 4,000 yards and 20 touchdown passes for the fourth straight season, and dealt with a constant rotation of receivers, running backs and offensive linemen fairly well. By the metrics the Lions wanted, he had a pretty good season and didn’t miss a snap despite being sacked 45 times -- almost double the sacks he endured in 2013. Oh, he also became the fastest player to 20,000 passing yards in league history.

The bad: So those completion percentage and interception numbers? Stafford’s numbers were still no better than the middle of the pack in a league dominated by passing. His QBR of 55.1 was 22nd in the league, and he held on to the ball longer this season than he did last year despite worse line play. His yards dropped for the fourth straight season, although he also had fewer attempts than he had in any full season he’s played. Stafford wasn’t particularly strong under pressure this season, with a 2.6 QBR (tied with Drew Brees for 23rd in the league) and his 37.6 completion percentage was 25th in the league (although Aaron Rodgers was 24th). His passer rating under pressure of 47.3 was 24th in the league under pressure.

The money (using 2015 cap numbers from ESPN Stats & Information): Stafford is the only quarterback the Lions have under contract, and he will have a $17,721,250 cap number in 2015. That is 25.8 percent of the offensive cap and 16.76 of the total cap. Of his $9.5 million base salary, $8 million is guaranteed for the 2015 season. Orlovsky and Moore, being free agents, could be brought back fairly cheap, and both have expressed a desire to return. If Detroit tries to make room for Ndamukong Suh, Stafford’s deal is one that could be restructured easily to free up some space. Actually, if the Lions really believe in Stafford as the quarterback of the future, his contract would make the most sense to restructure.

Potential cuts: The Lions aren’t cutting Stafford, so none. The bigger question will be what they do with Orlovsky, Moore and potential other quarterbacks in free agency or the draft.

Draft priority: Not especially high this season. However, if the Lions choose to move on from Moore or Orlovsky, there could be room to draft a quarterback late to develop. But investing anything more than a late-round pick here would mean ignoring other, more pressing, needs.
