No, the inside box focuses on neutralizing the opponent's best outside scorer. Off course this does not mean that u cant use it against an inside tactic. To be honest I haven't tested it alot against look inside or low post to have a solid conclusion. Dont be afraid to use it though it is a good defense overall but like every zone it will have its pros and cons. My advice is if u have guards with 5-8 ID just play man to man otherwise play any zone that suits you. The 2-3 zone is definitely working better against look inside after the update
