Local LB

Dallas (Hillcrest) linebacker Earl Thompson (6'1", 207, 4.5) lists SMU, along with Kansas, Kansas State, Oklahoma State and Texas A&M. I've seen him in person, and he's a terrific player - sometimes taking over games. However, I wonder if he will grow enough to be a college LB. If that 4.5 is legit, maybe he's a safety who's playing LB for now?
Does anyone know how highly regarded he is?
