Signing day is in the books, and spring football is just weeks away. This week, we're taking a position-by-position look at where teams are heading into the spring. Next up, let's rank the league's offensive lines as they stand today.

1. Alabama: Three starters return (guard Ross Pierschbacher, center Bradley Bozeman and tackle Jonah Williams). As usual, high-level talent is incoming via recruiting, such as five-star tackle Alex Leatherwood and ESPN JC 50 tackle Elliot Baker (the top-ranked junior college tackle in the country). Both are early enrollees and could play right away. Add them to the cupboard full of linemen whom the Crimson Tide have recruited in recent years, and Alabama is still in pretty good shape, even though Cam Robinson and Alphonse Taylor are gone.

2. LSU: Ethan Pocic and Josh Boutte graduated, but there's still plenty of talent returning that has starting experience. K.J. Malone and Will Clapp, who started on the left side of the line, are back. Toby Weathersby and Maea Teuhema, who both logged starts at right tackle, also return. Add to the mix ESPN 300 tackle Austin Deculus, the No. 5 offensive tackle prospect in the 2017 class, and the Tigers aren't wanting for quality options. Replacing an All-American at center, which Pocic was, will be the key challenge.

3. Auburn: The Tigers have three quality starters returning: Austin Golson, Darius James and Braden Smith. But the Tigers lost two talented ones in Alex Kozan and Robert Leff. Auburn added three offensive linemen in its 2017 recruiting class, including ESPN 300 offensive tackle Calvin Ashley (6-7, 310) who might be able to play immediately.

4. Missouri: The Tigers are in great shape up front, returning all five starters from a 2016 group that allowed the SEC's fewest tackles for loss and sacks. The Tigers bring in a large recruiting haul, so the depth is plentiful here.

5. Arkansas: The Hogs return four of the five starters, including Frank Ragnow, one of the nation's best centers. Finding a replacement for left tackle Dan Skipper, an All-SEC selection who graduated, will be the toughest task.

6. Florida: Four starters return for the Gators: Martez Ivy, T.J. McCoy, Tyler Jordan and Jawaan Taylor. Left tackle David Sharpe declared for early entry into the 2017 draft, so that spot must be filled. But it could possibly be done by moving someone already starting over to that spot (possibly sliding Ivey over from left guard or move Taylor over from right tackle).

7. Ole Miss: Robert Conyers, who started at center last year, is the Rebels' only departing starter up front. Ole Miss was young and should have a smooth transition to 2017, with Greg Little, Javon Patterson, Jordan Sims, Alex Givens and Sean Rawlings all returning.

8. Texas A&M: The Aggies lose their two starting offensive tackles but return the entire interior starting offensive line, which was young and had its ups and downs in 2016 but performed solidly for the most part. Finding tackle replacements will be the most pressing issue this offseason; junior Koda Martin likely figures into one of those spots.

9. Kentucky: Replacing Jon Toth, a four-year starter at center who was a leader and a mainstay at an important position, is the toughest task. Bunchy Stallings, who started at right guard last year, might be the answer, but there are other options, including 2016 ESPN 300 recruit Drake Jackson. The other three starters from last season -- tackles Cole Mosier and Kyle Meadows and guard Nick Haynes -- are all back, as is Landon Young, the Wildcats' top 2016 recruit.

10. Tennessee: This unit needs better play in 2017 than it had last season, but at least there is plenty of experience. Tackles Brett Kendrick and Drew Richmond, guard Jashon Robertson and center Coleman Thomas all started last season. The Vols brought in a significant talent haul in its 2017 recruiting class, led by ESPN 300 No. 1 overall prospect Trey Smith, an early enrollee.

11. Georgia: The Bulldogs lose three starters (only starting guards Isaiah Wynn and Lamont Gaillard return), but the good news for the Bulldogs is that the 2017 recruiting class is heavy on linemen: Kirby Smart signed six. At the top of the list is ESPN 300 No. 2 overall prospect Isaiah Wilson, who should compete for a starting spot immediately. ESPN JC 50 No. 2 offensive tackle D'Marcus Hayes could also play right away.

12. Mississippi State: Three key starters are gone -- Jamaal Clayborn, Justin Senior and Devon Desper -- but there are players with starting experience returning, particularly at the key offensive tackle spots. Martinas Rankin, who started at left tackle last season, returns, as does Elgton Jenkins, who has started at both tackle and guard. Starting guard Deion Calhoun also returns. A pair of junior college offensive linemen who are already on campus, ESPN JC 50 Tommy Champion and guard Tyre Phillips, should compete for immediate playing time.

13. Vanderbilt: The right side returns (guard Bruno Reagan and tackle Justin Skule). Ean Pfeifer, who started the final nine games at left guard, also returns. The Commodores must plug holes at left tackle and center. There are three 2016 offensive line recruits who redshirted last year and four offensive tackles whom the Commodores signed in the 2017 class, so reinforcements are on the way.

14. South Carolina: The Gamecocks bring back four starters (only left tackle Mason Zandi departs) in 2017, but it's a group that gave up an SEC-high 41 sacks and second-worst 102 tackles for loss. Dennis Daley, the No. 3 junior college offensive tackle prospect in the country, will have a chance to compete for a starting job once he arrives, and he could be a potential successor to Zandi at left tackle. D.J. Park, a senior who started three games last season, could also get a look at that spot.
