Watch the play again and that looks true, too. Ozigbo isn’t selling the run-fake at all. He’s getting to the flat. Both tight ends, Carter and Sam Cotton, end up going out on routes as well. Did Armstrong know it wasn’t a pass but then tried to turn it into one as a reaction?
That we don’t know right now. Armstrong didn’t talk after the game. In the grand scheme of things, the answer doesn’t matter much anyway. It doesn’t change anything. The point is there was confusion.
Good teams are not confused at that moment.
