the Braves had several options, but they break down essentially as follows:
1. They could run their existing inventory of relievers and pitching prospects, who were already on the books, to see if players who had performed well in past years or who have high upsides would perform well this season.
2. They could deploy additional financial resources in the offseason to address what did seem like a possible need.
During the season the Braves spent 13m on Dallas Keuchel and according to the AJC, they added about 7m to the payroll in acquiring the three relievers. Anthopolous says he required approval to go over budget to do so, but let's say that on opening the day the Braves had roughly 20m dollars of additional leg room for in season acquisitions.
What does it look like if the Braves had spent money during the offseason on higher level relievers.
Let's say they signed someone like Adam Ottavino (8m) or David Robertson (10m) and someone like Sergio Romo (2.5m) or Greg Holland (3.25). Let's call it 12m.
I would have probably been pretty pleased in the offseason had they done that as that was essentially the kind of finishing moves that I thought made sense.
That would have left them with 8m to play with during the season (for purposes of this thought experiment, let's dispense with "Liberty should spend more, etc"
8m would have been insufficient to sign Dallas Keuchel, which is something that became necessary because of very unexpected poor performance by the starters.
It's also entirely possible that they would have signed someone like Robertson who basically had no impact on his team this year. Which would have ended up not addressing the need at all, which would have the same hole to fill, less 10m dollars available to fill it.
Say what you will, the Braves started the season with a lot of relievers in the system who had performed decently in past years. While there were injury risks and definitely risks of players not holding performance, the Braves had a lot of guys and a lot of pitching prospects to help them fill that gap. I think in retrospect, with the benefit of hindsight, it was entirely logical for Atlanta to cycle through their in house options while retaining the flexibility financially to address any need that came up through the season.
As we see, doing so did not stop the Braves from building a large lead in the division and it did not stop them from addressing the pen at the deadline at relatively little cost. the benefit of waiting meant that they at least acquired arms who were performing well in 2019. I'm not sure that guarantees good performance down the stretch and in the playoffs but at least it gives you a better sense of who these guys are at this moment in time. They're not injured, they've not lost a step, they're currently performing guys.
This is another instance of where the superior patience of the Braves front office allowed them time to find the effective guys they had in house, while also giving them the ability to deploy all their resources to improving the critical needs of the team that might arise.
But you say, what if things had gone poorly and the Braves had built themselves a hole? They could have made in season adjustments earlier (in fact they did pick up Swarzak for one) to short it up. But it never got so bad that it was necessarily.
