You'll have to find a player with atrocious outside and inside defense.
there was a last season that nowitzki hold hs opposition(in regular season), to very low point per game(or shooting percentage) even top 20 in the league. Probadly cause Chandler, haywood take the most dangerous inside threat but it is still impressive. I think his defence is pretty underated in public view, and yes i was surprised to reading that.
And to get back on topic, i don't know if he is close to Nowitzky in any areas but one of my backups works very well for his salary and i am pretty sure could dominate lower divisions:
(4701310)Jump Shot: strong Jump Range: respectable
Outside Def.: strong Handling: respectable
Driving: average Passing: strong
Inside Shot: tremendous Inside Def.: sensational
Rebounding: prodigious Shot Blocking: mediocre
Stamina: average ↑ Free Throw: respectable
Experience: strong
I could play him 20 min in BBB on PF/C, without the opponent take advantage of him with a relative cheap salary. For Nowitzky like action maybe add a bit more JS, at least that would be the improvement i would give him when he would be younger.
