Sealing the edge and protecting the quarterback is what these guys do best. Here are our projections for the SEC’s starting left and right tackles for each team in the Western Division this season and their impact on each respective unit:

RELATED: Projecting the SEC East’s starting left and right tackles and their impact

Western Division

Alabama: Cam Robinson and Dominick Jackson — After starting every game as a true freshman last season and earning All-America honors, Robinson — along with center Ryan Kelly — headlines what should be a stout wall of protection for quarterback Jacob Coker this fall in Tuscaloosa. The right tackle spot won’t be decided until August, but Jackson, a former JUCO transfer, appears to have the edge over Ross Pierschbacher. At 6-foot-7, 320 pounds, Jackson has the size to perform and will try his best to match the production left by Arie Kouandjio who started 27 consecutive games on the right side.

Arkansas: Denver Kirkland and Dan Skipper — The Razorbacks have shuffled a few starters on a unit that gave up the fewest sacks in the SEC last season and finished fifth in rushing at 218 yards per game. Kirkland has moved from guard to left tackle to help Skipper transition from the left to the right side to replace Brey Cook, the only starter the Razorbacks lost up front. An interesting note on Skipper is that he has used his 6-foot-10 frame to block four field goals during his career. With those two bookends, Brandon Allen should have plenty of time to operate in his final campaign at quarterback.

Auburn: Shon Coleman and Avery Young — Young is Auburn’s versatile veteran, having played several positions in the trenches with success during his career. The senior has 19 starts at tackle and a couple at guard, but the coaching staff believes he is best suited on the outside. Coleman has overcome a leukemia diagnosis in spring 2010 to make a name for himself on the Plains. He has blossomed from lottery pick Greg Robinson’s former backup at left tackle to a pancake waiting to happen at the edge.

LSU: Jerald Hawkins and Vadal Alexander — Replacing left tackle and projected 2015 first-round pick La’el Collins won’t be easy, but LSU will have extreme depth this fall in case something goes wrong with Hawkins’ move from the right to left side and Alexander’s slide from guard to right tackle. Alexander hasn’t played tackle since his freshman season, but says it’s a natural fit. The switch shouldn’t be as noticeable for Hawkins who got reps last fall behind Collins as the blind side protector. The Tigers return three starters along the offensive line but each will play new positions. Les Miles is just happy that Hawkins and Alexander decided to skip the draft and return.

Mississippi: Laremy Tunsil and Fahn Cooper — Anchored by Tunsil, arguably the SEC’s most talented tackle who is returning from injury, the Rebels’ offensive line is the only unit in the SEC that returns all five starters from last season’s team. Tunsil will manage the left end when he returns to full strength while the senior Cooper, a former JUCO transfer, secures the right. Cooper is however being pushed for playing time by sophomore Christian Morris. Much of the spring practice talk up front has centered around freshman Javon Patterson who could play a major role inside at one of the guard positions.

Mississippi State: Justin Senior and Rufus Warren — Faced with the task of replacing four starters along the offensive front, the Bulldogs are relying on Senior to step into a leadership role as a junior after starting 12 games at left tackle last fall. Warren is penciled in to replace mainstay Blaine Causell on the right side, but Elgton Jenkins and Cole Carter should have a say during fall camp. A converted tight end, Warren has a year under his belt at his new position, a spot vital to the Bulldogs’ success on the ground this season without frequent tackle-breaker Josh Robinson toting the football.

Texas A&M: Avery Gennesy and Germain Ifedi — Ifedi has right tackle secured as one of three returning starters, but there’s a vacancy at left tackle left by Cedric Ogbuehi that’s up for grabs and likely won’t be decided until mid-August. There’s pressure on Gennesy to perform as the potential starter considering the three players before him have all been drafted in the first round (if Ogbuehi continues that trend in April). Jermaine Eluemunor will get reps too.
