Via KCCI, these are new secondary logo designs that apparently went out last fall, but nobody noticed because ISU didn't exactly announce it. Hey, you figure it out:
Technically, these are just secondary logos; the I-State thing is still going to be on the helmets and the Hilton floor and everything; this is just for people who like having a birdy on their shirts. More power to them, I guess.
At this point, shouldn't the Cyclones just take the last step and just call themselves the Angry Birds? Isn't that a better idea than it has any right to be?
