Ok, a couple of things come to mind.
1-I highly doubt that AD Osbourne would say ok given the name of Iowa's stadium, statue, speech played at the beginning of each game, etc.
2-The only way I see Barta sort of being ok with it is that if Nebby gets it, the joke's on them. I doubt he says ok, chuckling while they sign whatever.
It seems like it will be based on the Armed Forces, which I think both sides would be good with. Also, it seems that the Iowa/ISU trophy will have to do with corn, so no point in that.
Obviously, it's based on pure speculation at this point. Hopefully they do something involving the Armed Forces that also involves both States' volunteers.
Either that, or whoever loses/wins, gets an extremely low flyover over their stadium.
