How much impact does setting your backups at getting tired and your starters at fairly fresh make on actual playing time/substitutions? Would having a high stamina player set for higher fatigue that is #2 at 2 positions make him more likely to say slide from the 1 to the 2 and give both starters a break before subbing back out? Is this a way to try to help moderate the hockey style line-changes that seem to occur in HD?

I try to do that sometimes and it does seem to work as far as keeping the sub on the floor for a minute or two at the second position he is a backup at. Obviously your starters staminas and freshness settings will play into how much time the super sub will play at either position.
