I'd advise against buying any jerseys from NFL.com until Nike takes over the apparel license in April. Reebok stopped making jerseys months ago, so what is being sold on NFL.com isn't by Reebok or Nike. I don't know who is producing them (they are being called "Pro-Line") but the quality is apparently poor and the jerseys aren't completely accurate either.
Secondly, the Super Bowl jerseys for the Patriots are only available in white, which makes no sense because they are wearing navy for the game. Darren Rovell of CNBC says this is due to shortages and the expiring Reebok deal:
Due to Reebok's expiring deal, there are NFL jersey shortages. The NFL will only offer Super Bowl jerseys in white.

Here is the link for the Pro-Line Super Bowl jerseys:
New England Patriots Jersey - Patriots Super Bowl Jerseys (XLVI), Authentic, Throwback & Replica Jersey
As you can see, only the white ones have the Super Bowl logo on them. The collar is also wrong (it should be navy and silver) and the striping down the sides is missing. Also, the wrong Super Bowl logo is used. What is shown on the NFL.com jerseys is using the regional logo (it has Lucas Oil Stadium in it); the actual uniforms will be using the national logo (no stadium):
A guy at another board I post at ordered a Pro-Line Gronkowski jersey and is returning it immediately. The shoulder numbers and lettering is screened on and the front/back numbers are weakly pressed-on. He said the quality is way worse than the replicas Reebok was making.
tl;dr Reebok's expiring apparel contract means Pats and Giants fans get dinked over on Super Bowl jerseys this year. Don't waste $90 on these low quality "Pro-Line" jerseys.
