If this is true, then the coaching staff is not living up to its duties because it goes against what Garrett allegedly promotes, i.e., competition to put the players who are deserving on the field. When Romo was ready, I wanted him to start, because 1) I don't think a starter should lose a job due to injury 2) he's a 10 year vet who was still playing at a high level 3) he even said this is the best team he's ever been a part of so it's a shame that he can't lead them to the end result 4) he's better than Dak right now 5) Dak is still young and has much to learn and be coached up 6) coaching staffs should stick to their principles instead of worrying about irrelevant buzzwords like "chemistry", "momentum", "going with the flow", and all other nonsense. After all, isn't it a "process"?
Or perhaps the coaching staff is just diabolical and they're just saving Tony as a secret weapon. They really know how good this team could be with him at the helm and want to surprise people come playoff time.
