Captains' Patches

I just bought an Adidas Panarin home blue jersey the other day. I wanted to get an Alternate captain patch, but I had a couple questions pop up in my search.

  1. I see some pics of Panarin with an A patch, and some without. I assume this is because NYR has had so many Alternate captains over the years, so they just rotate out who wears the A's on any given night. Does anyone know how they switch off? I saw an old post from back when they had 6 A's saying that they have 3 guys that wear it at home, and 3 others that wore it on the road, but I'm just curious how it works now.
  2. Does anyone have a reliable source for AUTHENTIC captains patches? I found one on ebay that looks pretty good, but it's for the 2016/17 jerseys, before the NHL switched to Adidas, so I'm not sure if it would totally match the current sweater. I also want to make sure whatever patch I get matches the stitching on the numbers, name and logo.
