Chuck Daly said that players stop listening after a while, I would say that Flip's message never sunk in. Flip knew what the job at hand was to win championships, and he didn't get the job done.
Indications are that Dumars won't stop here. Expect the core 5 to be changed as well. All but McDyess have high trade value. See Freep.com for the local papers take on this situation.
The bottom line is that the pieces were there to get the job done, but Flip didn't get it done. Coaches are hired to be fired. Michael Curry is rumored to be high on the list of replacements, but he sure is short on experience. (Only one year as an assistant, here in Detroit.) But he will do what Dumars wants, which would be giving lots a minutes to the young players on the bench.
It will be interesting to see what direction Dumars goes in. Will he be looking to stay competitive right away, or will he be looking to be competitive in 2 seasons with younger players? Hiring Curry might be an indication of the direction, easier to throw a first time coach under the bus with a developing team, than an established coach like Avery. It will be an interesting off season.
By the way, Your Beliefs, I agree 100% with what you said, as does Dumars.
