And that's a valid opinion, and I'd agree on the lack of effort front. However, to play devils advocate, the numbers you point to then could be due to a lack of effort then and not a lack of athleticism. And lack of effort can be corrected in off-season coaching. That does bring up an interesting point though as the numbers you are using can also point to odd overall team stats which can make a player appear worse than they actually are. There is an adjustment made to the BPM metric to equivalate overall OBPM to the teams adjusted team offensive rating. Since DBPM is simply BPM-OBPM, this means that high performing offenses with the same defensive stats ostensibly result in worse DBPM without actually being worse. Peter Jok is a perfect case study here going from a DBPM of 0.7 his junior year to a DBPM of -0.4 his senior year. His rebounding numbers increased substantially, he got his steals, and he even blocked a couple shots, however, his numbers went down due to his team's statistical offensive improvement. It's a weird statistic that can be useful, but is probably less useful in extreme cases like having a great offense and a terrible defense.
I never claimed that athleticism is 100% how well can you dunk a basketball. I am going to stand by the fact that there is a correlation though and that it is one of the less subjective measures. I will certainly concede that there are other measures of athleticism, just not ones we have available to see plainly on tape. It's very hard to get at measuring athleticism.
This post had nothing to do with athleticism.
