The NFL mock drafts keep rolling in, with subtle changes reflecting player movement and Pro Day results.

With less than three weeks remaining until the first round of the actual draft, the consensus for who the Detroit Lions should take with the No. 5 selection appears to be shifting toward Central Michigan offensive tackle Eric Fisher.

Below is a collection of 16 mock drafts that have been updated over the past week.

Eric Fisher, OT, Central Michigan: With long-time left tackle Jeff Backus retiring and the Lions moving on without right guard Stephen Peterman and right tackle Gosder Cherilus, Detroit must create a cohesive front if their investments in Matthew Stafford, Calvin Johnson and free agent addition Reggie Bush are to flourish together. Fisher, who some rank as the top talent in the draft, would make the task of fixing the offensive line much less daunting.

Eric Fisher, OT, Central Michigan: A no-brainer for the Leos. Detroit needs a long-term replacement for the retiring Jeff Backus, and here sits Fisher, who has his Michigan connection and a draft grade that puts him in the same neighborhood as the No. 1 overall pick, Joeckel.

Dee Milliner, CB, Alabama: The Lions can plug a leaky pass defense in two ways. They could target a needed pass-rusher here, or they could go after the best cornerback in the draft if he's available. If Ansah is off the board, Detroit can sprint to the podium with the assurance that it has upgraded at cornerback, which is the second-biggest need for this team. Milliner is ready to start and succeed early, and defensive line depth in this draft should have the Lions confident they can add pass-rushing value in Round 2.

Luke Joeckel, OT, Texas A&M: The Lions are tasked with replacing both of their starting offensive tackles from last year with the retirement of Jeff Backus and Gosder Cherilus signing a free agent deal with the Colts. Joeckel would be able to plug in at left tackle and give the Lions a long-term starter to protect Matt Stafford.

Bjoern Werner, DE, Florida State, Junior: In desperate need of outside pass rush help, the Lions debate between Ezekiel Ansah and Bjoern Werner. While Ansah may be a more explosive athlete with more potential, Werner is a more polished and ready player and the Lions need to win in 2013 to keep the head coach and general manager from being fired.

Eric Fisher, OT, Central Michigan: Jeff Backus retired and another tackle from the state of Michigan is available. A few NFL line coaches continue to tell me they like Fisher more than Joeckel.

Peter Schrager, Fox Spots

Eric Fisher, OT, Central Michigan: Gosder Cherilus and Jeff Backus won't be back with the Lions, so look for the team to upgrade its offensive line. A lot of folks I've spoken to like Fisher as much as Joeckel, if not more. The 6-foot-7, 310-pound road paver might not be around at fifth overall. If he is, look for the Lions to keep him in-state.

Ezekiel Ansah, DE, BYU: (No explanation)

Todd McShay, ESPN.com

Eric Fisher, OT, Central Michigan: (No explanation, but McShay made slight adjustments to his previous version after the Matt Flynn and Carson Palmer trades. Last week, McShay had the Lions selecting Ansah.)

Pete Prisco, CBS Sports

Eric Fisher, OT, Central Michigan: Jeff Backus is retiring, so they get a replacement.

Akbar Gbajabiamila, NFL.com

Eric Fisher, OT, Central Michigan: The Lions could use an all-around talent on the offensive line like Fisher. (In college, he started at multiple position.) This pick sets the tone for Detroit's draft and the 2013 season.

Clark Judge, CBS Sports

Eric Fisher, OT, Central Michigan: This one is simple. The Lions need someone to cover Matt Stafford's back, and Fisher is one of the best two tackles in the draft.

Will Brinson, CBS Sports

Barkevious Mingo, OLB, LSU: Losses on the defensive line -- particularly at defensive end as Cliff Avril and Kyle Vanden Bosch departed this offseason -- means a need to grab a pass rusher. Mingo needs to add weight but could make an impact early with Ndamukong Suh and Nick Fairley occupying blockers.

Walter Cherepinsky, WalterFootball.com

Ezekiel Ansah, DE, BYU: The Lions need defensive end help with Kyle Vanden Bosch getting cut and Cliff Avril entering free agency. If they can't get any pressure on the quarterback, Aaron Rodgers is going to continue to shred their secondary, no matter who is starting back there.

Eric Galko, Sporting News

Eric Fisher, OT, Central Michigan: With Jeff Backus retiring and recent draft pick Riley Reiff destined for the right side, staying in-state and adding a franchise left tackle should allow Matthew Stafford to take the next step as a top-flight quarterback.

Bob McManaman, AZ Central

Ezekiel Ansah, DE, BYU: I had the Lions taking Utah defensive tackle Star Lotulelei last time out, but Ansah, whom I had going one pick later to Cleveland, makes just as much sense. The Lions will be looking for pass-rush help after cutting Kyle Vanden Bosch and losing Cliff Avril to Seattle. They also need help on the offensive line, though, and the interesting thing to note here is that Fisher is still available. The Cardinals must be foaming at the mouth right about now if the draft unfolds the way I have it going.
