So now you care about fit and roster construction? your argument was that Bron wouldn't make the finals with the 2015-2017 Warriors. Well, Curry wouldn't make the finals with most of the teams Bron made the finals with. Bron has a better chance of making the finals with those Warriors teams than Curry has making it with any team Bron has made the finals with.
The competition? The Warriors made the WCF in 2016 without Curry
they won two consecutive playoff series with minimal contributions from Steph.
