The Ravens’ offseason has been a sea of change. Quarterback Lamar Jackson got a new contract, and Baltimore got a new offensive coordinator and a cadre of new wide receivers. But there’s also a familiar face among all that restructuring. Tee Martin, who spent the past two seasons as Baltimore’s wide receivers coach, was named quarterbacks coach in February, taking over for James Urban. For Martin, it’s a return to his natural position — he quarterbacked Tennessee to a national championship in 1998.
