Makes sense. I feel like the 2d jerseys should be a 3rd jersey before becoming our main jerseys.
I would imagine it's a logistics thing.
I'm not 100 percent sure on the entire process, but I know Adidas/Reebok requires a specific amount of time before a jersey can be retired, and that the actual creation of a jersey is a longer process than just throwing out a photoshop and saying in April "we want that by October". Unless I've lost count, next year will be the start of our 3rd year wearing these home jerseys. So it's possible that we have to wait 3 full years before actually retiring them. I don't remember if Adidas/Reebok's number of years for how long a team has to keep a jersey is 2 or 3 years.
I don't think the Heritage Classic counts with that 3 year rule because it was a special event jersey that was already created. We chose to re-use it as our 3rd this year, but it was already made. We didn't have a 3rd made and ditch it a year later.
Other people with more knowledge, probably
@BonkTastic could probably clarify.
