Posted this on another thread, but the move makes perfect sense. Jerry Jones is going to let Jason Garrett play out his contract and coach for his job next year, the final year of his contract. You can’t bring in outside coaches to take an OC position in what is effectively a one-year job.
So they’ll promote from within and see what Garrett can do. It’s interesting, you’ll have three former NFL quarterbacks on the coaching staff.
I presume that Garrett would need to get at least to the NFC Championship game to get a contract extension next year.
