We will have to wait and see how much this damages Adidas. However, I would surely believe both sides would have the ability to get out of a contract if one party does something to damage the reputation of the other.
Problem is.....if all hell breaks loose and it gets bad enough to get out of the Adidas contract, we aren't in a really big bargaining position with either Nike or Under Armor.
We could EASILY end up with a worse contract than the one we currently have. (and I'm fairly happy with that one).
