Nets, Cavs eye Thornton-Jack deal

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

The Nets, amid fears that they'll be unable to re-sign Shaun Livingston in free agency, have identified Jack as a prime target to either help fill the void or improve their backcourt versatility.

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.
