Nike knows what they're doing. They sell replicas of the jerseys worn on the field. If Nike released them for sale, they're what's going to be worn on the field. The athletic dept. screwed the pooch by not having an unveiling/press conference before they were available for sale.
FWIW, I actually saw them at Kansas Sampler. They have high-quality K-State stuff.
(despite the fact that I'm a cub, I know what I'm talking about jersey-wise, though I don't have any inside contacts. I'm kinda uniform OCD.)
