Some background analysis of other title winners and teams that fell just short.
I looked at the number of fairly major and minor moves the last five (first time) title-winners made in the two years before the victory (draft, free agents, trades).
I found they made almost 17 total moves, 8 of which I quickly and loosely called fairly major (had some impact, played 15+ minutes per game or so).
So the teams that win titles make a lot of moves in the two years before the title.
Then I looked at OKC, Orlando and Cleveland (last three teams to get to finals but not win a title, yet).
They made an average of about 14 moves, only 6 of which were fairly major.
So the teams that fell short made fewer moves and fewer fairly major moves than the title-winners.
But they still made a lot of moves. So there is not a good basis for saying they were standing pat, showing simple patience. They made moves. But maybe not enough and enough major ones.
