Tulane’s depth chart at quarterback became perilously thin behind starter Jonathan Banks on Tuesday when Khalil McClain announced on twitter he was transferring.

McClain, a strong-armed 6-foot-3, 220-pound freshman who played in two games this past fall, joined rising sophomore Johnathan Brantley and senior Glen Cuiellette as departures since the season ended, leaving Banks as the only returning scholarship quarterback.

As a result, Tulane’s pursuit of former Zachary High star Lindsey Scott figures to ratchet up even more with the Jan. 15 deadline for midseason junior college signings approaching fast. 

Scott, who chose LSU over Tulane two years ago, transferred to East Mississippi Community College this fall and led his team to the National Junior College Athletic Association championship after making little headway on the Tigers’ depth chart. He visited Tulane in November, Kansas in December and also has offers from Missouri, Western Michigan and Texas-San Antonio.

Missouri likely exited the picture when standout quarterback Drew Lock elected to return for his senior season instead of declaring for the NFL draft this week, but Scott has given no indication where he is leaning. He has three years of eligibility left.

McClain beat out fellow freshman Dane Ledford for a third-team spot in preseason drills and had four series of mop-up duty in relief of Brantley during a 56-14 loss to Oklahoma in September, a game Banks missed due to injury.

Banks returned the following week against Army, but when he had to leave for a play on what turned out to be the game-winning touchdown drive in the final minutes, McClain replaced him instead of Brantley.

Brantley returned to his role as top backup for the rest of the season, and McClain did not play again. He finished with one completion for 11 yards in three attempts, rushing nine times for 3 yards.

Elon (North Carolina) Western Alamance quarterback Christian Daniels, a two-star prospect, signed with Tulane in December and will enroll in the spring semester. The Wave also could shift Ledford back to quarterback for spring practice after he moved to wide receiver in September.

Tulane offered a scholarship this week to Riley Smith, a 6-foot-5, 210-pound prospect from Jacksonville (Florida) Bartram Trail High.
