How exactly did they get complacent?.
You're not being serious are you?
For the series the teams were about even on open looks. GSW was slightly better.

I don't see how this is relevant to my argument, considering I was speaking about the amount of open shots they received and didn't make, specifically over the last three games (I already stated that the Warriors defense couldn't stop the Cavs - bringing up their open looks doesn't hold any weight here).
That's quite clearly a significant drop from the playoffs as a whole (47% on 24.5 open shots - second most in playoffs - only behind T'Blazers) and the regular season (50% on 25.3 open shots - third most in regular season - only behind Wizards and Clippers). They got relatively the same amount of open looks during those last three games as they've been getting all season/playoffs long but were just missing more than they usually do.
The Cavs weren't shutting them down for long stretches at all. Warriors were shytting the bed on offense by not capitalizing on open shots like they normally do.
BTW notice the Warriors shot just about the same on open shots in this year's Finals as they did last year (slightly better in some areas ex. wide open 3s).
That was until the last three games when they started making their open shots in the '15 Finals:
First three games - 41% on 24 open shots per game
Last three games - 49% on 21 open shots per game
The Cavs were actually giving them less open looks (contrary to popular belief) during those last three games when GS went 3-0.
They missed more as the series wore on, you don't think that had anything to do with the Cavs strategy, extremely physical on defense, attacking Steph on the other end, closing off the paint etc.? Granted something like is just about impossible to quantify. Could just be they ran extremely hot early in the series and regressed to the mean as the series grew longer.
Less that and more the playoffs taking a toll on them physically and mentally (most certainly in Barnes' case), going through a cold run and complacency (they've been guilt of this all season long - it just so happened it came back to bite them at the worst time) because they executed when they needed to against a more physical and better defense during the WCF.
