I don't know for certain. but inside shooting is a form of jump shooting in a way, it just not from much range. Please correct me if im wrong.
if I play patient and the best player is center during the game then he will get the ball a lot, regardless of jr/js. its abut the mis-match of skills. I have had my center get most point plenty of times, in my current league, his jr/js is nothing to get excited about. bx1 is a good defense but I think with the right team playing it it cn be effective, but I learned you need that exact skill on the bench as well to actually run it,, the offense tactic should be one that puts mass points on the board.
