Apparently, the party's over for New York Knicks shooting guard J.R. Smith.

Smith is off to one of the best starts of his nine-year NBA career and on Thursday he cited a cutback in nightlife as one of the key reasons for his success.

"I'm not going to lie. The New York City nightlife pretty much got to me. I was going out pretty much every other night and not focused on the task at hand," a candid Smith told reporters in San Antonio after the Knicks' morning shootaround.

Smith said that a new, disciplined approach to practice has helped his performance for the 6-0 Knicks.
