No, you're right. Dallas had a 3rd round grade on him, but he wasn't drafted until the 7th round by Minnesota. Considering that the Cowboys could have drafted him in the later rounds (What sensible team doesn't draft a player graded that high in, say, the 6th?) or put in a claim for him once he was released, I'm guessing this may have been another case of the coaching staff overruling the scouting department. And that seems like it was the right call.
