Lue got his job because he holds LeBron as accountable as any other player, according to that Windhorst book, one of Blatt's problems was he was inconsistent in how he handled his superstar and eventually gave up and turned that over entirely to Lue which convinced the Cavs front office to just get rid of Blatt if LeBron and Lue were going to coach the team anyway. Because Spoelstra had already been coaching Wade and plus had Riley backing him up that issue did not develop in Miami and a lot of the tea leaf reading people were doing during the first title year was the legitimate development of a relationship between Spolestra and LeBron, regarding trying to destagnate the lulls of that offense through the shared love of watching video. (Spoelstra started out as Miami's video coordinator.)
This is year four for a lot of these guys, and many of the additions were guys who have been on other contending teams, they're also older. They're coasting hard, which makes their offense kinda nuts.
They slid hard last year too though, and then tore the East apart on the way back to the Finals. They were 26-7 to start 2017, then went 14-9 to sit at 40-16 after the first game out of the All-Star Break, then went 11-15 the rest of the way to finish 51-31. Their point differential fell from +8 to +3 from Jan to the end of the season.
That fourth year and last Miami team started off clunky, then had a ten game win streak early in the year and was 27-8 and even 43-14. Before finishing 11-14.
I assume Lue remains unless LeBron says otherwise. They're paying him $7 million a year until 2022. Plus Dan Gilbert fired Mike Brown without consulting LeBron last time and it turned out LeBron was okay with Brown and totally uninterested in Byron Scott. So he might hesitate a little this time.
