The Brooklyn Nets and Cleveland Cavaliers are discussing a swap of guards Marcus Thornton and Jarrett Jack, according to sources briefed on the talks.

Sources told ESPN.com that the Nets, after acquiring Thornton at the trade deadline in February, have identified Jack as a prime target for increasing their options at point guard.

Thornton has only one year left on his contract, which would appeal to the Cavaliers as they attempt to create as much salary-cap flexibility as possible for the summer of 2015.
