That setup seems to support the idea of making STOP a position, with the Archetypes being Blocking and Coverage. Those could also be the two SA trees,
Blocking - Run Block, Get Low, Hands, Cut Block, Pancake
Coverage - First Step, Change Direction, Wrap Up Tackle, Diving Tackle, Monster Hit
doing this is a must... make STOP a position, but have one more tree for return man, so there can be a returner who isn't a CB or a HB or a WR, but just a pure return specialist... List STOPs on roster down with kickers and punters rather than with the offense or defense.
