There are basketball shooting drills to work on all types of different areas of shooting; footwork, game situation shots, etc. The Backboard touch shooting drill is going to work specifically on the players shooting mechanics, touch, and getting them warmed up before playing a game, or before basketball training. When the player does the drill though they really need to be focusing on their mechanics and staying mentally engaged, otherwise it is just a time waste.
Because this shooting drill is only going to be at half speed, it allows the player to take their time and really lock in on their shooting mechanics. Also using the backboard makes the player focus on shooting every shot with arc on it, and it teaches them the value of using the backboard. Players like Tim Duncan have learned the value of using the backboard and by using it have mastered the mid range shooting area. Another great thing that this shooting drill will work on is the players footwork coming into the shot. Since it is at half speed it will help them practice the correct footwork.
