What rule would a player violate for rerouting of an opponent?

[Art N]

This does seem like a loaded question. HTBT for sure.

You have to be sure that it is the defender who is making the contact and running into the offensive player or is the offensive player actually trying to cut into the defender.

I can picture a defender making a bee line from hoop to hoop to get down the floor as fast as possible, and an offensive player is in the outside "lane" begining to angle towards the hoop and contacts the defender trying to get to "his intended path", which happens to go through the defender. OOPS
