Brute force is really as much about the computing power as it is the clever use of it. Thanks to Amazon AWS, Google, Microsoft Azure and RackSpace there's plenty of brute force to access if you can pay for it.

Using the averages is fine when you have an huge set of things to break and in this case you have basically 1. So you must consider the outlying minimum.

Then there's the issue that you don't know how well the encrypting software salted or what quality the source of randomness was it used.

All in all I wouldn't be at all surprised if it was well within the ability of a nationstate to crack that between now and kickoff.

Not sure how badly you want to know this game you'd go through all that trouble.
I can think of about 20 ways off hand that would be far easier to find out the field design or the whole game a lot easier.
No - I won't elaborate because saying not to give yourself an unfair advantage is all that needs to be said.
