NFL coaches and GMs lie. All the time.
It’s just part of the job. In a sport full of hyper-paranoid individuals who will do anything to gain even the slightest edge, there’s no benefit to being honest and every potential benefit to simply lie or at the very least, obfuscate the truth. Be it through coach-speak, blatant word salad, or a meaningful deflection, the coaches and general managers of the National Football League are never known for their transparency or vulnerability.
If you’d like a shot at getting the most honest version of those notoriously dishonest people, though, the best time to ask them a question in a formalized setting is the end-of-season press conferences.
