So whose blocked shots are the most valuable? Mr. Huizinga closed the presentation by going over what he calls “Block Value.” To determine block value, he used the formula Points Saved + Points Created where Points Saved equals the effect of a Block on Opponents Expected Points during this possession and Points Created equals the effect of a Block on Own Team’s Expected Points During the next possession.
Using this formula, we found out who had the best season since the data started being collected (2002-03) in terms of overall block value. It ended up being Theo Ratliff during his 2003 season. Ratliff ac ulated a block value of 300 (287 coming from points prevented while 13 came from points created), which when transformed into wins ends up being right around 5.
Interesting Numbers
Just thought it would be interesting to include some numbers towards the end of Mr. Huizinga’s presentation, showing how number of blocks can’t really be used when determining who is the best “shot blocker.”
So why was Mr. Huizinga’s paper called From “…Dwight Howard to Tim Duncan?” Well as he explained, through a series of charts,
Tim Duncan has had the best season in history when it came down to value/block with 1.12, meaning he saved 1.12 points with every block and Dwight Howard ended up with the worst season in terms of value/block with with .53 (both came during the 2008 season).
