This is a fallacy -- losing to Cleveland was just the tip of the iceberg; though for some reason people like to spin it as the sole reason. We all knew Thibs was on thin ice long before the playoffs even started. There were indicators of poor communication between him and the front office for at least 2 years. Then you add on their (and many fans') displeasure with heavy minutes load to injured players, unwillingness to play certain guys, etc. We heard about several players (3 starters IIRC) advocating for Thibs' departure in post-season interviews.Strange that a coach was fired last season due to the front office being "disappointing" that it could not beat the team that went to the finals and now 20 games into "Hoiball" the talk is of blowing up the team. Nice slight of hand, that.
Notice these things have nothing to do with his ability to rack up wins or even his basketball intelligence. By all indications he is a brilliant hard-working basketball mind who is also stubborn as a mule, and perhaps too old school for his own good. People need to stop comparing Thibs to Hoiberg based on reasons that had no connection to why Thibs was fired. Hoiberg was brought in to change the culture to one that is more conducive to long-term success. You should always expect causalities with that big of a change. I would also focus on things beyond just W/L record after 18 games; e.g., are we playing with more pace, reducing turnovers, sharing the ball better, etc.
Also as an aside -- I don't see any (rational) fans saying to blow up the team. Trading Pau Gasol for an upgrade at PG is not blowing up the team. Though I do agree he is undervalued by many fans, and we'll be hurting for some inside scoring the minute he's out the door.
