Some way, somehow, something needs to change to allow Romo to deliver the ball faster. He's likely going to continue getting hit by onrushing defensive linemen if it continues. Dak is delivering the ball more expeditiously than Romo. He appears to make his reads quicker. It affords him the advantage of putting defenses at a serious disadvantage due to the lack of time for them to adjust. I think Romo is simply dealing with too many options to be as efficient as he might be otherwise. I not too sure Jerry did him or the team a big favor by allowing him to make as many last second adjustments as he does.
I think the problem, and evidenced by his nature that everyone has seen, is that he's just too much of a competitor for his own safety. He's going to look to make a play every single the ball is in his hands, body be damned.
Unfortunately, at his age, the body isn't going to stand up to what he's willing to throw at it. The staff is going to have to reign him in and really get through to him that he can't help the team on the bench, and he absolutely has to get the ball out faster. I think sitting on the bench not helping the team is probably killing him, so I'd expect him to try and do that even though it's against his nature.
If you gotta give him tough love tell him if he gets injured again, that's basically hamstringing the team for two years with his cap numbers, and a smart team would be looking to trade his contract next year when they have a guy like Dak. Some men take some tough love sometimes.
