If the Braves were at the 85 win mark on the win curve, I would agree with getting a short term fix at 3b they could pencil in for 2-3 wins.
If they had plans to improve the team to the 85 win level, I would agree with acquiring a more dependable answer at 3b.
However, all signs and comments point to the Braves having very little money to add anything this offseason. Their "big" signings are likely to be a BP arm or two. Those improvements aren't enough to get this roster anywhere near 85 wins, so i would like them to "see what they have" with Camargo, just like they did with Adonis. The main difference is Camargo at least has a chance to be valuable, whereas it was beyond obvious almost immediately that Adonis wasn't the answer.
The Braves have shed a good bit of payroll this year. Even with some raises, I don't think it's out of the question what we could have anywhere between 20-25 million available, may be more depending on if we can move any salaries.
