The SB has not so important role like IS, ID, RB, or do you think in another way?
Do you rather have a player with IS 19 and SB 7, or a player with IS 12 and SB 14? Its an easy choice I think.
If you have a strong ID your player don't need to block the shoot, he can defend normal and don't let the offensive player to score.
What I'm trying to say, 2-3 zone should be much more efficiently vs Inside Tactics.. need higher ratings than now in your ID.
This is where we hold them!
