Andre Drummond pulled down 17 rebounds on Wednesday night, the eighth-highest total by any N.B.A. player this season. Yet his rebounding average for the year dropped.

Drummond, always a great rebounder, is off to a historically great start on the boards for the Detroit Pistons this season. His numbers are striking.

■ After establishing himself at 13 to 14 rebounds a game during the past two seasons, Drummond has increased that to 19.3 this season. That would be the highest average since Wilt Chamberlain averaged 21.1 in 1968-69.

■ Drummond has 57 offensive rebounds. The next highest total is 30, by the Knicks rookie Kristaps Porzingis. Drummond is on a pace to have the most offensive rebounds since Moses Malone in 1978-79.
