Should everyone in a NBA team be super tall? Or a team can benefit having diverse set of players?
In this article, we'll take a look at NBA diversity in regards to height and BMI (weight-height ratio)
and how they have been changing since 1980 till present days.
Average height trend line doesn't seem to change much (maybe just a little upward). On the other hand - we can observe dispersion becomes less of a thing since 2000. The cluster though means - there is still difference from one team to another, however as time goes by - we see less of super tall or super short players.
Here we have certain upslope with its' peak around 2010. As we talk about atheles - we can rely on the assumtion that weight comes from muscle mass rather than fat. That's being said, we can conclude that that players work out in GYM way more, and average player is about 22 lbs (10 kg) heavier than before.
The data is not certain as of course physical measurements are not main contributors. However even here we can observe a trenline. A team with average between 6'6" and 6'8" (199-203 cm) together with standard deviation of 0'2" - 0'4" (6-11 cm) yields best results in Playoffs
The distribution is flat, meaning on a given timeframe - weight is less of a factor for the game. Nevertheless we have around 198-231 lbs (90-105 kg) average with 13-35 lbs (6-16 kg) standard deviation.
What it gives us in total? There is no golden numbers that bring a victory, however the analysis
provides us with some kind of boundaries. If I were given a task to build up a team - I would go
with 6'7" +-3" (200+-8,5 cm) height and (98+-12 kg) weight.
My starting lineup would go then as:
POS | H (ft) | H (cm) | exemplar |
---|---|---|---|
PG | 6'3" | 191 | K. Irving, D. Lillard |
SG | 6'5" | 196 | R. Allen |
SF | 6'7" | 201 | K. Leonard |
PF | 6'9" | 206 | M. Beasley |
C | 6'11" | 211 | T. Duncan |
