For all those John Hollinger fans, Miller told me he uses his own statistical system to assess a player’s value and contribution.
It’s pretty simple: Add up points, rebounds, steals, blocks and assists. Subtract fouls, turnovers and shots taken. Then divide by minutes played. This gives you what Miller calls a player’s batting average, to borrow from baseball.
Miller can figure it out approximately in his head after every game. When we talked, he was excited that Andrei Kirilenko’s batting average for the Jazz’s first preseason game (10 points, eight rebounds, four blocks) was .583. He’s now at .490.
A player with a batting average of .300 usually approaches All-Star status, Miller said. A player with a .400 average is definitely an All-Star and a player with a .500 average is a likely MVP candidate. Karl Malone’s career average, which Miller cited, was .457.
Appearantly, it’s a very effective measuring tool
What’s remarkable, Miller said, is how accurate he believes the formula to be. That’s part of the reason the Jazz calculate it at the end of every season for every player in the NBA, then cross-check it against a couple of other statistical ratings.
Over the years, it regularly spit out John Stockton as the NBA’s top point guard, Michael Jordan as the top shooting guard, Larry Bird as the top small forward, Malone as the top power forward and Shaquille O’Neal as the top center, Miller said.
Update: A year forward, Dave Berri compares his WoW stat versus Miller’s – link – which appearantly produces very similar results to Berri’s stat.
