My theory: I think Gillis recognized that we needed to rebuild, but Francesco Aquilini was having none of it. The Sedins were only 3 years removed from career seasons and were signed for a few more years. FA probably thought that with the right mix, the Sedins could carry the load for a couple more years.
So he goes out and hires JB and explicitly tells him he's not to do a rebuild, that they wanted a competitive team with butts in the seats for the playoffs. JB does what he can for the next couple of years to win now, much to the chagrin of the fan base that, quite correctly, had been calling for a rebuild. JB becomes the focal point of fan ire, when really he's just following his marching orders. This attempt to retool leads to the precipitous decline of the Sedins and an unintentional rebuild. I speculate that last season was when FA finally came around to the realization that the Sedins were done and the team absolutely needed a rebuild. I think they signaled this when Linden used the dreaded 'R' word.
A lot of that is true and the timeline is right. The only things I'd add are
a) JB wasn't forced to not rebuild but rather not rebuilding was his plan too. He was hired because he didn't want to rebuild, he and FA saw things the same way.
b) Nobody made JB make bad moves. It is one thing to not rebuild, it is another to make bad errors of judgment while trying to execute it.
