I'll give Bynum a pass, because of the way he moves. Like people have mentioned how Dwight doesn't need to be learning from the likes of Hakeem, because he's more clunky than Hakeem. He needs to hit up the likes of Shaq, or his freaking coach, McHale.
Same with Bynum; he's not a finesse guy. Very clunky. That sort of style, you can't really 'hustle' with his style, you know? I mean, you can, but his movements aren't as free.
But Dwight? I know I just compared his agility to Bynum, but that's not to say that Dwight is un-agile (word help, please). Dude won one dunk contest, and entered like.. what? Three of 'em? Dude is crazy 'athaletic' (no Barkley). If he was out there hustling like J-Hill, it would be CCCCUUUUURRRTTTAAAAAAIIIINS for the league. Lights out. Shut the league down. Sorry, LeBron; O'Brien goes through Dwight. He could be rebounding like Rodman/Ben Wallace, but scoring like David Robinson. And I know people give DRob hell, but that's my dude. Before Kobe's 81, he had the highest game since Wilt (70-something). He has like a handful of near quadruple doubles. MVP. Two championships. Sure, not until Duncan came along, but dude definitely had his time. AND THIS WAS WHEN THERE WERE ACTUALLY OTHER CENTERS IN THE LEAGUE. Hakeem. Shaq. PATRICK. They all took turns collecting rings (well, except Ewing, but he was still an absolute FORCE).
This SHOULD be Dwight's time.
But no. THERE ARE NO CENTERS IN THE WHOLE FREAKING LEAGUE. It ain't like he's up against Dream, Diesel, & Patrick.
It's SO FRUSTRATING watching him and knowing how long he has been in the league. Like you said, Bargnani freaking clamped him last night. He should be FEASTING when he's facing like 90% of the league, since centers are virtually gone.
Watching him get blocked by Bargnani last night, losing positions for rebounds, watching Lin get through... it's just frustrating watching him, then seeing a guy like Hill be productive despite not being anywhere near as athletic and skilled and smart as Dwight.
