The only SA I bother with on a FB is Lead Block. Unless the bonus is huge, I just can't imagine a little bit of extra energy loss is really going to be a big deal if just one guy has it.
I know Bort wants to make energy and morale more important and turn up the penalty for having low stamina. It would be interesting to see a team put lots of Hands on their linemen and compliment it with 2 RBs with Punishing Runner, but I damn sure wouldn't test out an offense built around unpopular SAs and VAs since it takes more than a year to get out of the minors.
