To get ready for free agency, we're going to take a look at each of the Detroit Lions' 2015 free agents. Next up is quarterback Kellen Moore.

2014 stats

Preseason: 4 games (0 starts) | 35-51 (68.6%), 361 yards, 3 TD, 0 INT, 1 lost fumble

Regular season: 0 games (0 starts)

How he joined the Lions

Signed as an undrafted free agent in May 2012.

Case for re-signing him

Moore, who is a restricted free agent, has shown flashes in the preseason before, and perhaps it's time to let him seriously compete for the backup quarterback job. He really outperformed Dan Orlovsky last preseason, and the Lions might as well give him a shot after keeping him on the team for three years. He'll come extremely cheap, and the Lions could always keep him around as the third-stringer yet again even if he doesn't win the backup job.

Case against re-signing him

Moore didn't dress in a single regular-season game in his first three seasons with the Lions. Although he's performed well in the preseason, the Lions just don't seem to feel comfortable with the idea of him being the backup, and if that is indeed the case, it's best for them to just move on and use that third QB spot to develop someone else. What's more, that third QB spot should be reserved for a player on the practice squad instead of wasting a roster spot on someone who never even dresses on game day.

Final verdict

There's really no downside to bringing back Moore. If he competes for the backup job and beats out Orlovsky or someone new, great. If he doesn't, he can stick around yet again as the third quarterback on the roster since the Lions are so insistent on having one. And if the Lions bring in someone else to compete at the quarterback position and Moore ends up being let go by the time the final cuts are made, no big deal.
