Working to clear the logjam in the backcourt, the Knicks are discussing their potential trade options with guards J.R. Smith, Iman Shumpert and Shane Larkin, a league source said Sunday.

“They’re working on trying to make a move in the backcourt,” the NBA source familiar with the Knicks’ thinking said.

The idea that the Knicks are trying to make a trade to balance the roster isn’t earth-shattering. President Phil Jackson and GM Steve Mills have mentioned the Knicks have a surplus in the backcourt, with Mills saying last week the Knicks are “heavy” at shooting guard.

The issue for the Knicks, of course, is deciding whom to send out in a trade and figuring out what they can get in return in such a transaction.

Tim Hardaway Jr. has been deemed virtually untouchable, per a source.

Smith, the 2012-13 Sixth Man Award winner, has a player option in his contract for $6.4 million for the 2015-16 season and is coming off what he called the worst season of his NBA career. As such, it is unclear how much interest he could draw on the open market.
