From a naive perspective, JB has been a lazy coach for some time.
Adopt the zone and apply it to all situations, so you don't have to scout or scheme for individual opponent players.
'Fix it at the half,' so you don't have to scout or scheme for individual opponent players.
Run Iso offense, so you don't have to create or teach offensive plays or scheme or scout for individual opponent mismatches or exploitation opportunities.
Explain that 'we just didn't make shots' so that you don't have to to teach/develop shooting/ball skills, or scheme to get players easier shots at more advantageous places on the court and/or within the shot clock.
Don't play away games unless absolutely required.
Don't recruit outside of a 2 hour flight region.
Don't hire non-alums, so you don't need to be challenged by outside thinking.
Unfortunately, sometimes the naive have valid and accurate perspectives.
This post will likely lead to some rabid responses, but i find it odd that some of us are so quick to defend the coach, but have no problem ripping the kids. Our players do the best they can with what they're given. We really need better talent in order to obviate our issues.
And what about the 'we don't need a different big man coach' thing? We need to both Get and Develop talented bigs. Who was the last center we had in the NBA? If the response is that the trend is away from the traditional post-up center, that's fine, but you have five players on the court, and we can't thrive with one of them being borderline incompetent. We aren't even getting good defense from them.
