Thats not really fair to say because the Braves signifantly improved their offense by calling up Swanson and acquiring Kemp.
Yes, a couple of players played real well but the Braves won a lot of games with a bad starting staff.
I think this is overly optimistic. The fact that Flowers, Garcia, Inciarte, Markakis, Freeman and Kemp all performed much, much better in the second half than they did in the first half, and in the case of most of them better than they ever have, is a reason to be concerned. In order to buy that the second half wasn't a mirage, you have to assume a number of things:
1) Freddie Freeman is going to be an MVP contender for years to come. He had a 177 wRC+ in the second half. I think Freddie will be a great player for us, but he was on a HoF pace in the second half. I don't see him coming anywhere near close to repeating that.
2) Adonis Garcia, 9 years into his career, has figured it out and is now an above average hitter, despite little improvements in his batted ball profile or K and BB ratios. I'm going to consider that unlikely.
3) Tyler Flowers can maintain a .387 BABIP and also maintain a big jump in his BB rate to remain a league average hitter.
4) Ender Inciarte is also suddenly an MVP candidate combining elite defense with a 120 wRC+. His .387 BABIP in the second half is unlikely to be sustainable.
5) Nick Markakis is better with the stick than he's been in 4 years. This has the best chance of being reality, as he at least wasn't that far ahead of his recent numbers.
6) Matt Kemp is suddenly an elite slugger again. Again, maybe this one could happen, but given how unlikely most of the other things are, it's putting a lot of hope in this happening to go all in right now.
Sure, it doesn't have to be all or nothing, and the Braves could still field a passable offense without repeating every one of these performances, but 4 of those 6 second half performances seem
highly unlikely to be even close. You'd have to be counting on Swanson curing a lot of ills if they don't.
