As far as the Pro Line jerseys found on NFLshop,com actually being the Nike designs, I am kinda doubting that. Nike will be releasing three tiers of jerseys. They will be known as Game, Elite, and Pro. Their price points will be $100, $135, and $250. Game jerseys will be equivalent to what is currently called a replica. It will have all screen-printed numbers and lettering. The Elite will then move you to what is now known as premier, which will have the tackle twill lettering and numbering. This is what they are currently selling for $100 as a Pro Line jersey, which is why I have my doubts as to this being the Nike product. The Pro level will be equivalent to the current authentic level, which is going to be a close replication of what is actually worn on the field.
