Well, unfortunatelly, Special Teams have a less important role in the engine i.e. less influence in the outcome of a game.
Of course, you're gaining or losing yards in punting situations, but special teams are less important than O and D on the field.

Nevertheless, if you have good punter on the field, he can give you some yards advantage. Same (but less) with Kick-Returners and Gunners.
For the STCBs, usually future Corners are set in order to gain BPOS before being set on the regular defense.

There should be eleven players on the field, but as I believe, just the special-team-members as set have an influence on the outcome of punting- and kicking-situations.

So, keep your focus on defense and offense, put your future corners on STCB and later on, maybe, buy a good kicker
