If those scenarios play out many expect Lashlee to take Miami offensive line coach Garin Justice and wide receivers coach Rob Likens with him to Dallas. Lashlee was the OC at SMU in 2018 and 2019 before being hired by Manny Diaz to come to Miami. Justice and Likens both have previous experience as offensive coordinators.
The Miami coaching staff is in flux with speculation that head coach Manny Diaz could lose his job once the Hurricanes hire as new athletic director. Miami could name the athletic director sometime this week. If Lashlee is hired by SMU he would likely leave the Hurricanes immediately and not coach in the Miami bowl game.
Justice and Likens coaching Miami in the bowl game or leaving with Lashlee immediately for SMU would be less sure. They could stay with Miami through the bowl game and then leave with Lashlee for SMU. If Miami is without Justice, Lashlee and Likens for the bowl game they would have a Spartan staff.
