Let's imagine this for a moment. This offense is susceptible to HUGE hits on the QB. Why? Because we throw it all the dang time. Now, Romo has a tendency to hold on to the ball a long time waiting for something big to come open. Romo has made a career out of big plays, not methodically moving it down the field. Callahan is not the one to be coordinator if we're going to preserve Romo's career.
Next season, they will put hit after hit on this guy from all angles. These guys are young and HUGE, and run fast. If he goes down, the doctor's could give him a give it up or die scenario (just an example). If he goes down, what's the plan? If he's forced in to retirement, what's the plan? Oh, find a sleeper in the 6th round who made trick shots with a basketball, or an ex baseball player? How about we trade for or pull a player out of retirement because Jerry wants to be the genius who thought of something no one else thought of?
This franchise is dead if we don't start the process of finding a future QB for this team. And take it seriously this time.
