To drive this point home, Mo Bamba’s defensive production at the next level may be more driven by his elite mobility than his wingspan. Understanding that wingspan differential doesn’t correlate strongly, defensive contribution most probably comes from a willingness to move. What jumps out the most is how strong of a correlation that distance traveled per game has to Defensive Win Shares, and to a lesser degree DBPM and DPIPM. Deflections, lunging for loose balls, and contesting shots all have clear correlations to Defensive Win Shares and to a lesser degree DBPM and DPIPM. If a player is already tall, then the impact of any extra inch of wingspan is negligible. Statisticįor big men in the NBA, height matters more than wingspan differential and it makes sense. Sources of each data point are linked in the following table.
The network plots give us better visibility as to which statistics seem to be most closely related. In order to help understand the findings in my initial correlational analysis by correlograms, I then plotted data on a network plot to help understand what the most important contributing defensive attributes. You’ll see what I mean in the table below. My initial question was: Does wingspan actually contribute to positive defensive contributions in games? The short answer is no, but by diving into correlations we should find the real reason behind what makes the foundations of a solid defense.Īnalyzing all players in the 2017-18 NBA season, I subjectively selected various statistics that are conceivably related to having a long wingspan and measured their correlations against each other. Size is nice though, isn’t it? If a player with great length, reach, or wingspan differential comes along, one would like to assume that a solid coaching system at the very least could turn that player into a solid defender. Outside of DBPM, there might not be a better statistic that gives us a guarantee for defensive success at the NBA level. Adjust the extensions in your hands until your wingtips are the length of your Albatross wingspan as you calculated above.A couple of weeks ago I had written about taking Ed Weiland’s draft standards into the modern era and had thought to add wingspan differential as a way to round out a college prospect’s defensive potential. Hold out your wing extensions in each hand and have a friend measure you from wingtip to wingtip. Attach sturdy sticks (dowel rods or perhaps measuring sticks) to the cardboard wingtips, using tape. Use the wingtips you cut out earlier to trace two wingtip shapes onto the cardboard, and then cut out two cardboard wingtips. Get a piece of cardboard about the same size of a piece of paper. What’s your albatross wingspan?ĭOWNLOAD AND PRINT THIS WORKSHEETto calculate how long your wings would be. Lay down and see how your own “wingspan” measures up!
How do you measure up to those wings?ĭOWNLOAD AND PRINT THIS PAGEto see how you compare to an albatross. After you print out the wingtips, tape one wingtip on the ground, and then measure 7 feet and tape the other wingtip to the ground so you can see the 7 foot albatross wingspan. Watch a video of a similar species of albatross flying on their long wings. Those long wings help them soar across the ocean with very little effort. The Short-tailed Albatross in the photo above has a wingspan of over 7 feet! This species is known to fly almost 2000 miles between their nests in Japan and where they forage for food in Alaska.
