BOCA RATON — The days of mixing and matching offensive linemen in fall camp appear to be temporarily over for Florida Atlantic head coach Lane Kiffin.

Three of last year's offensive line starters — center Junior Diaz, guard BJ Etienne and right tackle Brandon Walton — return for another year, although Walton moved to left tackle after All-Conference USA selection Reggie Bain's departure. Redshirt sophomore Nick Weber replaced Florida transfer Antonio Riles at right guard to start spring camp, but missed the final two weeks with a staph infection.

FAU also added Auburn tackle Calvin Ashley through the transfer portal. Ashley will play this year as a redshirt sophomore and is working to secure a waiver from the NCAA so he can immediately play.

Junior college transfer Lavante Epson, who spent spring camp as a second-team guard, won't be a part of the action. Epson entered the transfer portal in June, only five months after he arrived on campus.

LT:

Brandon Walton — Sr. (6-foot-5, 300 pounds): Walton has quietly grown into one of Conference USA's top offensive linemen, even if his lack of recognition on the all-conference team say otherwise. A strong senior season could make Walton FAU's first offensive lineman selected in the NFL Draft.

Doug Johnson — R-Fr. (6-5, 320): Johnson is being groomed as the Owls' future left tackle. He played in two games last season and is viewed internally as a future all-conference lineman.

LG:

BJ Etienne — R-So. (6-3, 310): Etienne started the Owls' first 11 games last year before missing the season finale with an illness. The former Park Vista and St. Thomas Aquinas standout was named to the C-USA all-freshman team and improved throughout the season.

Ean Biancardi — R-Jr. (6-5, 285): Biancardi began his career at tackle but is likely to play inside this fall. Biancardi was limited last season with a broken thumb and played in seven games two years ago.

C:

Junior Diaz — GS (6-2, 300): Diaz will enjoy the rare pleasure of participating in two Senior Nights with the Owls come November. The former Tulane starter was expected to be one-and-done as a graduate student last season but received a sixth year of eligibility. Diaz started all 12 games last season.

Jake Jones — R-Jr. (6-0, 295): The Seminole Ridge alumnus was named one of the team's most improved players this spring. Jones climbed his way up the depth chart last year and played two games.

RG:

Nick Weber — R-So. (6-3, 295): Weber worked his way into the 2018 lineup as a rotational lineman and started in Etienne's place against Charlotte. The Parkland-Douglas grad is expected to be ready for the start of fall camp after his offseason injury.

Deon Humphrey — R-So. (6-3, 310): When Weber went down, it was Humphrey — a walk-on from American Heritage — who took his place. Humphrey will be the first man called on if Weber has any setbacks this season.

RT:

Calvin Ashley — R-So. (6-6, 322): Ashley played five games at Auburn last season. ESPN ranked Ashley as the No. 6 offensive lineman and 32nd best overall prospect in the class of 2017.

or

Marquice Robinson — R-Fr. (6-3, 315): Robinson was the Owls' starting right tackle in spring camp and impressed in run blocking. It'll be Robinson taking Walton's old spot on the outside if the NCAA denies Ashley's waiver.

The big question: How much of a role will familiarity play? FAU returns three starters from last year and Weber, although he only started once last year, still was credited with snaps in all 12 games. FAU won't run into last year's issue of needing to build chemistry after losing three starters from the 2017 team. That's good news for Kiffin and new offensive line coach Jeff Norrid considering FAU's other questions on offense.

Name to know: Weber. FAU has had success with walk-on offensive linemen becoming dependable starters in the past. Weber moves well for his size — he's credited playing basketball and lacrosse in high school for his strong footwork in the trenches — and is ready to become a long-term starter at guard.

The pressure is on: There was pressure on Walton and his position change, but he quickly ended some of the early concerns by dominating at left tackle in spring camp. There's no reason not to think FAU will feel safe with Walton on the blind side when the Owls open at Ohio State on Aug. 31.
