I think the rule is that they can recover fees if you sue them, right? Jerry didn't sue the league. I wonder how they plan to argue this. Also, they didn't enforce this rule during the deflategate issue. So you have a rule that is decades old, and you are trying to recover legal costs from someone that did not sue you, and this is after not enforcing the rule in a much bigger case. Yup, the league has a great case!
I really hope Jerry fights this to the end but we know that won't happen. The other owners want Jerry to suffer a little bit at least.
