Both exited via the transfer portal and there is promise but mystery at the position this season. First-year coach Tosh Lupoi filled the vacancies with highly rated but inexperienced transfers in redshirt freshman A.J. Tuitele from USC, redshirt sophomore Tristan Jernigan from Texas A&M and redshirt sophomore Kamar Mathudi from Oregon. But in limited playing time off the bench at their previous schools, the trio combined for nine tackles last season. Bob Gregory, retained by new coach Tosh Lupoi as the Bears’ inside linebackers coach, says he’s excited about all three newcomers.
