Can an authentic owner tell me what this (from the product description) means?
A jock tag, I'm pretty sure, is a label on the *outside* of a jersey and has the company name and size (XL, L etc.). On replica jerseys you can see them, as it says, on the outside on the lower left hand of the jersey.
I don't believe I've ever seen an authentic with a 'jock tag'. The Senators' store at Scotiabank Place has authentics for $299 (no name, number). I'm almost positive that there was no jock tag.
Check out River City Sports' web site. Choose NHL, a team and then "Jerseys (ALL)". You'll see the replicas with the jock tag, but the pictures of the authentics don't appear to have them.
