Is it not implied? The Braves never classified their 70s throwbacks as alternates in the style book. Heck, until a few seasons ago, they weren’t even an annual thing. To me, that’s not an alternate, whether specified or not. We agree on that (I think).
OK, we see Schiller suggesting they created the throwback look for the CC unis because they’re now prohibited from wearing the 70s throwbacks due to the 4+1 rule. That seems to suggest that anything—even a throwback worn for a single game or series—counts against the 4+1 rule, and couldn’t be worn if you’ve already got 4 uniforms in your style guide (which the Braves do).
But hey, maybe my reading comprehension is garbage and I’m missing something here. I’d love to see the throwbacks for Hank Aaron weekend later in the season (and maybe we will!), but it sure seems like the City Connects are a replacement for those unis. Anyways, moving on…
