I went ahead and e-mailed the seller, and he is very legit. He is close personal friends with Glenn Abott, and Dave Humm dated his sister when he was in college. He has a direct line to the current Nebraska equipment manager and authenticates all of his auctions. He pointed out another of his auctions that is a jersey that was not game worn. The game jersey is out of my price range, but I can afford the practice jersey. Thanks for the comments.
