That's true, but Doyel explicitly states that he had a "private conversation" with Schertz last night, and that he and the team will be going to St. Louis. That, at the very least, implies that Schertz told this to Doyel.
Now Doyel could be using turns of phrase to hide that he also talked to Ross Chaifetz who fed him this info, he and just attributed it to Schertz. Wouldn't surprise me. But the interview definitely sounded like he was saying, "Josh told me this."
And "journalists" wonder why trust in media is at an all time low. Maybe if they weren't just interested in clicks, and actually told the truth? Nahhhh...
