Texas A&M has many question marks entering the 2016 season and like every team, there are positions on the field that must be tended to quickly.

On defense, the most pressing need is replacing a pair of seniors at both cornerback and defensive tackle. There are talented backups at each position who will need to seize their opportunities.

But that’s still not the biggest concern as the Aggies look ahead to the 2016 season. It’s the other side of the football that causes the greatest angst. Three-fifths of the offensive line must be replaced before the new schedule kicks off.

Tackle Avery Gennesy (6-foot-5, 310) started every game this season and will be the leader on an otherwise inexperienced line. The JUCO transfer from Mississippi came to College Station after leading an offensive line that carried East Mississippi Community College to the 2013 National junior college championship, averaging a NJCCA-best 62.2 points per game.

After that, though, it’s up for grabs. Freshman Keaton Sutherland (6-foot-5, 301) started seven games at a guard and played in 12 games. He’ll be the most experienced lineman returning next season. He’s one of a group of candidates who will vie for playing time at guard in 2016.

Two more JUCO transfers are among the Aggies’ most experienced along the offensive line in 2015 who will attempt to answer some of those questions at the guard spots. Jermaine Eluemunor (6-foot-4, 315) played in 12 games this season and got his first start in the Franklin American Mortgage Music City Bowl against Louisville. He was a 2013 second-team All-Northeast Conference at Lackawanna College in Scranton, Pa.

Jeremiah Stuckey (6-foot-4, 300) is the only other lineman with starting experience. The California product played in six games in 2015, starting five of those, after making his way to Texas A&M from the City College of San Francisco.

Freshman Connor Lanfear (6-foot-6, 315) played in 12 games this season and though still looking for his first start, appears to have a bright future and further the competition at guard. Redshirt freshman tackle Koda Martin (6-foot-6, 302) played in seven games during the 2015 campaign and hopes to vie for his first start in 2016 as well.

Among the long list of hopefuls along the offensive linemen for the Aggies include junior tackle Ryan Lindblade (6-7, 308) who saw action in three games this season.

Sophomore J.J. Gustafson (6-5, 285) who got into two games during 2015, and freshman Erik McCoy (6-4, 315) could vie for playing time at center.

How it all shakes out remains to be seen, but anxious eyes will be on the Aggies’ offensive line as spring ball approaches. If the Aggies are to return to its usual fast-paced, high-scoring offense, this group must step up and gel in a hurry.
