Could Calathes return to Europe in 2015?

Nick Calathes struggled during his rookie season in 2013-14 and there was some speculation that the Memphis Grizzlies would waive him, but that didn't happen in mid-July. As a result, Calathes' 2014-15 salary worth $816,482 was guaranteed. Calathes is working hard to improve his game and is hoping his sophomore season goes better than his rookie year. Calathes will be a free agent in 2015 and if he can't get a good offer from the Grizzlies he could head back to Europe.
