Depends on what system you use. In zone blitz scheme your safeties have to be able to handle deep middle and also be able to rotate into the deep 1/3rd. All Depends on which way you roll your secondary. If you are playing cover 2, or 2 deep safeties your safeties need to be very speedy so they can cover 1/2 the field each. If you are playing 8 man front in either even or odd front, one of your safeties needs to be physical enough to roll into the box and handle both TEs and OTs coming off those nasty combination blocks. And when you get into nickel many of your rules change unless you use one of the zone blitz schemes where all is necessary is to rotate different players into different positions. But Smith does have the needed physical nature to handle WLBer, question is can handle the game moving at faster pace and less time to react. Some kids can and some have problems handling it.
