Does your defense make sense?

I was speaking with a coach the other day and discussing team defensive philosophies.  Many teams in our area influence players to the baseline when the ball is located on the wing free throw line extended, but will 3/4 front the post on the high side.  To me it doesn't make sense to tell your post player to play on the high side 3/4 and be able to give baseline help. 

Another one that hear all the time is they want their players to be in the passing lanes and deny, but then get upset when defenders one pass away can't properly support a drive.  Maybe I'm not demanding enough of our players, but I don't think you can consistently deny one pass away and support a drive with the same defender.

Another one that I struggle with as a coach is if we are influencing baseline on the wing and then decide our ball screen rule will be to force a player to use a screen and never let them reject it.  That would be a completely different stance than we normally teach.

The purpose of this post is not to tell you what your defensive system should look like, but to get you thinking about your defensive system.  Go through all the different scenarios you anticipate seeing from offenses this season and make sure your rules make sense.
