You are allowed to foul as long as you do it fluidly, and all of our guys are awkward.
The rules say (and the officials call the opposite):
--A defender who is straight up in his cylinder has a right to his space if his feet are planted, even if an offensive player dives into him or trips over his legs.
--You are supposed to be called for a foul if you use an elbow to clear out (damian jones this game) or push someone out of the way to get a board. Only foul called is when someone screams and over jumps a rebound, regardless of whether or not they were pushed.
--When a guard forearms a defender to create space or to fend off a big man to create shooting room, that is an offensive foul.
--PS: the last 2 minutes awful calls on murray and poythress "travels". If your pivot foot is down it isn't a travel.
