David Blatt has been diagnosed with multiple sclerosis, according to a statement posted by his current team Olympiakos.
Blatt, who was the Cavs coach from 2014-16, has been with Olympiakos since June 2018.
"I am a coach and my job is to lead and teach and inspire a lot of people. Not being as agile or active doesn't affect my ability to do those things. How could I possibly complain? I absolutely cannot and will not. It's wasted effort and while I ask my players and staff to be the best version of themselves, I must ask and even demand from myself to do the same," said Blatt in a statement.
