The video above comes courtesy of the excellent SLC Dunk, in a similarly excellent post detailing the workings of the flex offense frequently used in Utah. The Nets utilize many flex-esque sets -- if you've watched the team lately, you probably recognize the double-screen look to get Joe Johnson an open jumper.
The passing hasn't changed; Williams remains one of the best creators in the game, able to whip a bounce or no-look pass to a slim target with ease, and occasionally he'll pull out a double-crossover move or hesitation that reminds you he's one of the most talented guards in the game. But the video above details a different Deron Williams: one more intentionally pushing the ball in transition, one that attacks the rim with more frequency, one that has dunked (Williams has yet to dunk this season).
Williams has fought numerous injuries since joining the Nets; he has bone spurs in his ankle, fought a bruised shooting wrist, and has had numerous bumps and bruises throughout the season. Williams feels he's overworked himself. Nets interim head coach P.J. Carlesimo has said he's probably sore. It's plausible that these issues have affected his game, and changed how he approaches the floor.
Still... that's a fun Deron Williams in the video above. Hope to see more of him in Brooklyn.
