This seems to confuse a good business idea/principle, with actual good business and based on what we know about the reported direct cost of the exclusiveS, lawsuit settlements and sales numbers since, the argument could be made that the way EA handled the NFL exclusive wasn't good business.
You seem to be referring to eliminating the competition through an exclusive as good business, in the general since, whereas I think SageInfinite is specifically referring to the way EA handled the whole process. In that context, again it can be argued, that EA could have done things differently and potentially made more profit.
