Let's see, one ring in 4 years. 5 to rebuild depending how much old furniture we keep around. That's 9 years with a Snake Oil Salesman's guarantee. We may court that 2 decade trendline again. History does repeat.
The thing is, we weren't going to contend anytime soon had we not traded for KG and Allen. Was Jeff Green and Al Jefferson going to lead us to a title?
They were able to take a respite from 20 years of "rebuilding", and got 1 championship, a second finals appearance, and a couple other very good teams that fell short because of injuries.
Now, we are potentially back where we were in 2005 and 2006. We will have a few decent assets, and are looking forward to cap flexibility. Now, we will need luck to get to the top again, but that was always the case.
One thing I have learned being a fan of a losing franchise for most of my life is that you can't take the good years for granted. You need to take them when you can, and then be prepared to make the moves to get back there as soon as possible.
Yes, there were some mistakes made, but that is no different from any other franchise. But we are still in a solid position to rebuild or reload, and who knows, we may not even have to bottom out first.
