Getthesenets,
I'll be the first one to admit that I was not in favor of firing Blatt. It's not a criticism of Lue, but not an endorsement of Blatt either. I thought - and still do - it was a move to appease whiny superstars. And at the time, I thought it was just convenient for the players to place the blame for uneven play on Blatt. I think Blatt was good for the team he was hired to coach - before LeBron returned. He took a team to the Finals & then had a 30-11 record. But for many reasons, Blatt never had the respect of his team.
IMHO, the NBA - more so than MLB & the NFL - is less reliant on a coach. For examples, see GS from the past two years, Miami, & OKC as prime examples.
Having said all that, Lue HAS made a positive impact. It took awhile, but he has found two good rotation sets. The players respect him as an ex-player. Lue stood up to LeBron & challenged Love. He has not panicked when the Cavs have been down & hasn't over-used LeBron like every other coach LeBron has had. Lue came highly recommended by Doc Rivers, so he has the possibility of being a very good coach. And possibly putting the Iverson image forever in the rearview mirror.
Lue told LeBron to STFU soon after taking over as Cavs head coach.
