Shaun Hill still hasn’t closed the door on a return to the Detroit Lions in free agency, but if Hill leaves for the St. Louis Rams or another team, the Lions might turn to the NFL draft for his replacement.

Lions general manager Martin Mayhew said at the NFL ownersmeetings this week that he “definitely would consider drafting a quarterback” to back up Matthew Stafford this year.

“The value in that is maybe you have your backup for the next three or four years,” Mayhew said. “Or, like some teams have done in the past, when you draft that quarterback and you develop him, then you can trade him for a draft choice. So that certainly is an option for us.”

The Lions typically carry three quarterbacks on their roster and have spent the past two seasons with the same trio: Stafford as starter, Hill as backup and Kellen Moore as third string.

Hill has played sparingly the last three years, attempting just 16 passes and appearing in four games. At 34, his future in the league is limited.

Moore, who signed with the Lions as an undrafted free agent two years ago, has yet to take an NFL snap and is entering the final season of his rookie contract.

Stafford’s place atop the depth chart is secure.
