I know this holdout and everything else has been long and tedious for everybody, but it's extremely huge for us. We're happy to be a part of the Cleveland family and just want to take it one day at a time."James wrote on Twitter: "So damn happy for my Lil bro!! Well deserved. Good things happens to good people. I can't express how happy I am for you brother!"Head coach Tyronn Lue addressed the agreement after the Cavs' 118-108 preseason loss to the Chicago Bulls on Friday night."It's great news," Lue said.
