It's certainly not all about effort but that's a key ingredient. First thing is always positioning while the play is developing, mainly on the defensive end. You have to have a feel for when a guy is going to shoot it and at times maybe get a read for where the carom will go........then it's all about wanting the ball and effort with the boxout and attack the ball.........
Give Niels credit, came in skinny and although he's not huge he is cut and much stronger enabling him to battle for rebounds with people larger than he.........he's done a nice job here!!
