Brookyn Nets guard Deron Williams' average points per game and assists per game are down this season from last, which he says has to do with injuries and the Nets system. Williams is averaging 17 points and 8.3 assists this season down from averaging 21 points and 8.7 assists last season. He is shooting a career low 38.8 percent from the field and 29.9 percent from 3-point range. "I was injured the first year (and needed season-ending right wrist surgery)," Williams said Monday via ESPN, a day before the Nets host the Jazz at Barclays Center. "I've really had injuries while I've been with (the Nets) the whole time. And didn't have the talent around me that I did (with the Jazz). "And that system (in Utah) was a great system for my style of play. I'm a system player, and I loved Coach (Jerry) Sloan's system. I loved the offense there. We could've been a really good team. We just weren't that good defensively as a group." Williams said he's played system basketball since he was in high school so he's still adjusting to Nets coach Avery Johnson's offense. "I grew up in high school, my coach wasn't one of those guys that would let us just throw out the ball and let us play," Williams said. "We were a system team. We had staple plays that we relied on. We were good at execution. In college (at Illinois), we ran the motion offense. A lot of cutting, a lot passing, a lot of screening, a lot of extra passes. I'm used to just movement. So I'm still trying to adjust. It's been an adjustment for me. But it's coming along." Williams added: "I believe I can adapt to anything," he said. "We're still a young team. Things don't happen overnight. It's still just December. We're working on it." WIlliams signed a five year, $98 million contract with the Nets before the season.
