I don't think it's common for people to voluntarily admit that they were wrong. My guess is that people will dig in and say that it was championship or bust. Anything else is unacceptable. Pretty wild expectations with a 34 year old Joe as the coach.
That's why Joe shouldn't have been named coach—pairing a rookie leader with a contending roster is a bad idea. The expectation were high; the Cs should've selected a coach to match those expectations.
Agreed. Because even Spo lost in his rookie coaching year with an absolutely stacked roster of Lebron Wade Bosh lol
Actually that was his fourth year as coach - he became head coach of the Heat in 2008, after being an assistant to Pat Riley since 1997. But it was his first year coaching the Big Three, and there were all the questions that Joe is facing now - why was Riley entrusting the Heat to a four year neophyte. They didn't think he could handle the egos. They didn't think he had the Xs and Os. Like some here crying for Brad to come back and take over the reins, many wanted Pat Riley to come back and not waste LeBum, Wade and Bosh's primes. Here's an example of an article from back then:

And that's a guy who had 10 years as an assistant coach, and four years as a head coach. So when you think about Joe, you can think one (or both) of two things: 1) as a rookie head coach with zero NBA experience and not even any major college experience, he's doing ok given the circumstances; and/or 2) how the hell did he get this job? What was Brad thinking?

The question for Brad now will be - can Joe pull a Spoelstra? Or is he starting from too big a deficit? Can they afford to waste Tatum and Brown's primes, not to mention Al's sunset years, while Joe learns on the job? Riley took that chance on Spoelstra and it paid off. But Erik had more experience than Ime did when he started coaching the Big Three who were in win-now mode. How confident is Brad that Joe's got what it takes for the long haul and can he afford the time?
