The Atlanta Braves would be wise to be opportunistic this winter.
It's not that the Braves have a bad roster by any means--on the contrary, their roster is one of the best in Major League Baseball at full strength. But they found out this season that things can fall apart fairly quickly if injuries mount, and the rest of the National League has never been better.
One place the Braves could sneakily look to upgrade is the bullpen, which was anchored by a dominant closer in Raisel Iglesias this season, but was only 40 of 62 in total save opportunities.
