People who took that POV (which included a ton of Pistons fans) tended to focus on his poor help defense and the team's on/off splits with him. Zach Lowe wrote about it back in December:
Lowe: Ten things I like and don't like, including Luka's LeBron dimes
Dude's been a house afire for about the last six weeks now, tho – basically since he wasn't picked for the ASG. His boxscore numbers have obviously taken a bump (especially FG%), but so have his underlying defensive numbers and on/off splits. He's honestly been the best center in the league since the start of February, and just freaking destroyed KAT the other day.
Two other points wrt "among the best rebounders ever."
First, in terms of total rebound rate, Drummond actually is the best rebounder in NBA history:
That doesn't include Russ & Wilt, but their rebound rates have been calculated by the quants and
Wilt and Russell's data are estimated data from
here,
here and
here.
Second, if Andre stays healthy and keeps rebounding at this rate for the next five years (1200 to 1300 rebounds per year until he's 30), he'll be somewhere between 13,500 and 14,000 total rebounds – top 15ish all-time.
At that point, even if he drops off a bit he'd be a good bet to join Wilt & Russ as only the third player in league history with 20,000 or more rebounds (Wilt & Russ got so many b/c the game was played at a faster pace in the 60s, and because teams shot a much lower % from the field – hence more rebounds available to grab).
Long story short: Andre had a disappointing half-season, but he's on track to be a Hall of Famer.
EDIT: And just FYI, he'll most likely pass Hall of Famers Kevin McHale & Alonzo Mourning in total rebounds the next time he takes the court, which is tomorrow at noon against the bulls.
2nd EDIT: Apparently Lowe wrote about Andre again at the start of March, highlighting all of the above. Just reading it now!
Lowe: The Lakers have no excuses
The work is showing up in subsurface numbers. The Pistons are destroying teams since late January when Drummond holds the fort without Blake Griffin -- segments that had been a weak spot earlier. Opponents over that stretch are shooting just 54 percent at the rim with Drummond nearby, compared to 61 percent before then, per NBA.com.
He has also stopped forcing offense. Drummond is averaging just 3.7 post touches per 100 minutes since his brief absence, down from 7.5 before then, per Second Spectrum.
This is the best stretch of Drummond's career. It's not a coincidence Detroit has won seven of nine. If Drummond keeps this up, Detroit is going to annoy someone in the first round.
