After a player cuts, does the corner person fill her spot? For instance, if the middle person passes to the right wing and cuts to the basket, the left wing should fill to the middle and the left baseline should fill to the left wing. This encourages some more movement and gets players switching spots.
I would encourage them to work for great shots. I also tell my team not to expect the first cutter to be open, because the defense is set. We want to reverse the ball before we truly attack. We want the defense to shift and move and then attack.
But, you're expectations might be high too. I wouldn't discourage those who freelance because it is harder to get those who follow directions to move beyond the directions and become players than it is to take the freelancers and give a little bit of structure. We have players make ill-advised cuts all the time, but I prefer that to five guys standing around…
