You'd have won a few more games but no important ones and have less of a farm system. And since you committed to winning without nearly enough talent you may well have drafted for floor and traded prospects.
Less of a farm system? The Braves still would have had Albies, Acuna and Maitan, and could have still drafted Allard, Soroka, and probably Anderson (who would have almost certainly dropped to them in the middle of the 1st round).
They would have Simmons instead of Swanson, and someone else in CF instead of Inciarte. And if they had decided to trade Heyward and keep JUp, they would potentially have Swanson and Inciarte as well.
Literally nothing they got as a result of the rebuild has amounted to much of anything...at all.
If we are playing the hindsight game that seems to popular around here, I think I would have preferred to see how that alternate reality went rather than what we have seen instead.
