Microsoft responded to criticism of its Surface Pro 4 tablet and the technology that it provides to the NFL in general, in a statement responding to New England Patriots coach Bill Belichick's public damning of the solution.
The defence is of limited value though. Customers will view the NFL solution holistically, and as a result the performance of the whole solution reflects on Microsoft and Surface, whether that's valid or not.
In effect what the NFL debacle shows to prospective customers is that in a high profile, globally visible deployment, Microsoft isn't capable of using its technology to deliver what the customer needs reliably.
If you were planning a mission critical or high visibility solution in your organisation would that encourage you to pursue a Microsoft solution based on that evidence?
