I'm sure there is something to that, but IMO I think Nurk is a better overall player. What whiteside does better is block shots, and finish strong.
I'd say defensive rebounding wise they're fairly equal (whiteside may have a small advantage). I think Nurk is a better passer and decision-maker with the ball, Nurk's better on the offensive boards (it's just harder to box him out), Nurk's got more of a post game in my opinion too.
All that said whiteside has been very good this year, I wouldn't really say the struggles are on him. He's got some holes in his game, but he does basically everything their asking him to do at a reasonable level.
about the rebounding, career numbers:
off reb rate: Nurkic 11.9%....Whiteside 14.1%
def reb rate: Nurkic 26.0%....Whiteside 34.5%
total reb rate: Nurkic 19.0%....Whiteside 24.3%
some other career numbers:
PER: Nurkic 19.1....Whiteside 24.2
TS%: Nurkic .529....Whiteside .594
FT Rate: Nurkic .368....Whiteside .379
block rate: Nurkic 4.5%....Whiteside 7.3%
def BPM: Nurkic 2.9%....Whiteside 2.3%
assist rate: Nurkic 13.2%....Whiteside 4.1% (Nurkic 17.9% last season; Hassan 7.1% this season)
turnover rate: Nurkic 15.7%....Whiteside 12.3% (you'd expect to see higher turnovers with more passing)
statistically, Whiteside has a big edge across the board until it comes to defense and passing. Now defensively, Whiteside is a better rim protector (he's obviously taller and longer) but I'm not sure that translates to overall better interior defense. Obviously defensive rebounding is a component of defense, so Whiteside has that going for him. But my thinking is that Nurkic is probably a better instinctive defender. I also think you need to weigh those DBPM numbers by the fact Nurkic played with much better defenders last season, on a better defensive team
I've been thinking that Nurkic's big advantage over Whiteside was how he fits with Dame and the Stotts offense, especially in the pick and roll. The Dame/Nurk two-man game was a thing of beauty last season, most of the time. But I was pretty surprised by the PnR/roll-man stats from NBA.com for Nurkic last season vs Hassan this season:
frequency: Nurkic 24.6%....Whiteside 31.4%
points/possession: Nurkic 1.13....Whiteside 1.17
eFG%: Nurkic 55.2%....Whiteside 61.5%
FT Frequency: Nurkic 18.9%....Whiteside 12.7%
turnover frequency: Nurkic 5.9%....Whiteside 8.2%
percentile: Nurkic 60.6%....Whiteside 60.9%
yeah, I would have bet that Nurkic would have a significant edge in these numbers; but he doesn't
I tend to think Nurkic is a better player, although I wouldn't give him as big an edge as many do, and obviously, the stats tell a story that conflicts with a Nurkic bias. Maybe Nurkic is getting too much credit, in minds, for being on a good team last year while Whiteside is getting too much blame for the current team. The Nurkic nostalgia might be too strong, and Whiteside's biggest issue is he isn't Nurkic. Nurkic had a lot more help inside last season than Whiteside had this season.
Nurkic's biggest edge is that he's more than 5 years younger than Whiteside, and has a lot of margin for improvement. Whiteside's upside is probably capped
