Knicks explore Smith trade options

While they acknowledge that a trade may be difficult to pull off, the New York Knicks in recent days began exploring the potential market for guard J.R. Smith, ESPN.com has learned.

Sources close to the situation said Wednesday that the organization has become increasingly frustrated with Smith's on- and off-the-court transgressions and may feel that a fresh start would be best for all parties.

One source with knowledge of the team's thinking said the organization has become "fed up" with Smith's erratic behavior.
