Jerry's got an interesting dilemma for sure, and I certainly hope they are weighing this properly.
I don't want to see Dak get replaced because of a bad game. That sends a message that he lost it by performance, and that's just not true. I don't want him thinking he messed up. I want him knowing he's just in training for a much bigger role soon.
Obviously, you can't replace him if they're just rolling along and he's playing great. But tough times lie ahead for sure. It's got to be done right, and with clear communication throughout.
You can see defenses slowly starting to figure him out a bit. Or more specifically, they're figuring out how Linehan is calling games with Prescott. If the offense gets slugglish, THAT is the best reason to make a change. To throw the league a major changeup right when they're getting Dallas zeroed in.
By next season, I have no doubt that Dak will have added new dimensions to his understanding of the offense and pro game. Romo knows that, and I'm pretty sure Dak knows it, too.
