Listen to what Orlovsky says around the 43 second mark. We have a similar mechanism in our offense. Once Watson recognizes the coverage he announces the route concepts to the team.
I'm saying it's possible at times Watson calls something that doesn't jive with the play called, the route concept shouldn't change the entire play. Just tweak it.
At the same time it is very likely the receivers understood the concept incorrectly.
But with the number of times we've seen two receivers in the same spot, new guys, old guys, Kekee, rumors that Hopkins ran the wrong route... I've got to believe the error was most likely on both ends.
