There are two things the Detroit Lions desperately need as the franchise tries to win its first playoff game in more than 20 years: Defensive linemen and offensive linemen.

Though it is somewhat likely the Lions will go with one of those positions in the first round of this spring's NFL draft in Chicago, where they go has varied.

In his latest mock draft, Todd McShay has looked squarely at the offensive line and taken the most versatile lineman out there: Florida State's Cameron Erving.

Erving would make perfect sense for Detroit because of how he plays. He's someone who will grade out as one of the best centers in the draft should the Lions -- or any team -- choose to use him there. Prior to this season, though, he was an offensive tackle for the Seminoles and did well enough there to start on a national championship team. His size, at 6-foot-5, 313 pounds, could move him to any position on the line if need be, including guard if the Lions feel comfortable with their tackle and center situations.

"When I made the switch, a lot of people asked me how I felt about it in terms of the NFL. That wasn’t on my mind," Erving said of the position switch last week at the NFL combine. "I mean, I’ve always been the type of person that does what’s best for the team. When I moved from defense (after freshman season) that was what was best for the team. And that’s how I did.

"As far as moving from tackle to center, it’s what the team needed at the time. So I did it."

Erving started his career as a defensive tackle at Florida State before moving over to offensive tackle in 2012. The other potential option here is if the Lions were to draft Erving -- or another tackle -- in the first round, this could potentially help the franchise move current left tackle Riley Reiff inside to guard.

General manager Martin Mayhew is all about versatility -- especially in this draft -- and Erving would present the most versatile player possible on the offensive line in the Class of 2015.
