I dislike all free agents in next years class. Not sure how we fill gigantic holes in corner of and catcher. So stop pretending we will be contenders nxt year. Sell the new park and albies and Swanson for a year.
I suggest you take a look at Francisco Cervelli. A career .285/.358/.391 hitter with above average defense (according to dWAR) behind the plate. He spent the majority of his career backing up Posada and McCann in NY, so he has about half the innings on knees of a typical starting caliber catcher.
He will be going into his age 31 season and should be the Braves #1 FA priority on a 3-4 year deal.
