5'11" is OK for HS LB, but not MVFC. Kid played a ton of safety too. Strong safety much more read and react than speed, plus his speed looks fine for level of HS competition. Problem is, we aren't sure what that is. Nice to watch Hudl videos of OH kids, because we know the schools and the level of the opposition.
Besides nobody has too many LB's. You need 5 or 6 to play plus as many as you can find for kick teams.
