Analysis: Win-win for Nets, Cavs, LeBron

The Brooklyn Nets will acquire Jarrett Jack and Sergey Karasev in a three-team trade with the Cleveland Cavaliers and Boston Celtics, sources told ESPN.com’s Marc Stein.

Marcus Thornton will end up in Boston.

What it means: The Nets help themselves while enabling the Cavaliers to open up max cap space to lure LeBron James. Jack essentially replaces Shaun Livingston, who understandably left for more money in Golden State. Karasev, 20, was the No. 19 overall pick in the 2013 NBA draft. That’s a really nice haul for Thornton’s $8.6 million expiring contract. At the same time, of course, James may be clobbering Brooklyn with Cleveland for the next several years. Still, this is a trade that really helps the Nets, so it is what it is.

The Jack file: Jack, 30, averaged 9.5 points on 41.1 percent shooting for the Cavaliers last season. He had his best season as a pro in 2012-13, when he averaged 17.2 points on 50.6 percent shooting for the Golden State Warriors during the playoffs. Jack is a point guard who can flat out score in bunches. The Nets have liked him for a long time. Jack may be able to play in the same backcourt as Deron Williams at times as well. It’ll be interesting to see if Lionel Hollins, who has started more traditional lineups in the past, would play both of them together for extended minutes -- or even start them. Jack is owed $12.6 million over the next two seasons and has a $6.3 million team option for 2016-17.

The Karasev file: Karasev is a 6-foot-7 shooting guard with a ton of potential. He played in only 22 games for Cleveland during his rookie season, averaging just 1.7 points. Here’s what ESPN.com’s Chad Ford had to say about the Russian when he was drafted by the Cavaliers: Karasev is a fantastic shooter with deep range. He’s also a great ball handler with a terrific basketball IQ. Ford did say that Karasev needed to add strength and is just an average athlete. A league source told ESPNNewYork.com that the Nets were interested in taking Karasev in last season’s draft. They eventually took Mason Plumlee No. 22 overall.
