Putting pressure on the ball and causing turnovers are an art form, some teams can do it and some can't because they don't practice it. Why should a team be rewarded with a possible possession change because of a stall call or shot clock. If your team can't pressure the ball to cause a turn over thats the coaches fault. Now, I am not opposed to shrinking the field in which you are allowed to stall. Use the boys box wnd the old get it in and keep it in rule. That would make it difficult for the offense, and a little easier on the defense, but still need skill on both sides
