By new set he just means a brand new set of clean jerseys. Most teams during an 82 game season use 2 sets of jerseys for about 20 games each and then bring in a new set for the playoffs.
Just thought I would mention, the purple throwback jerseys (which will be worn again only on 3/9) will not be auctioned on NHL.com. I would suggest you contact Meigray if you want one as they started making their request calls.....
