Jones and Son Incorporated and Tony had thought all along that he would play out this contract and, potentially, retire at its conclusion depending on his health.
The team also had thought all along they would be paying both Tony and for a back-up QB, probably in the neighborhood of $3-5m/yr through 2019, and then would turn the corner to the next someone.
So, just from a budgeting perspective, for all the talk, the situation hasn't actually changed that much on the ledger--mostly just a discount on what they thought they'd be paying for the not-Romo QB since Dak's on his rookie contract.
That's why when Jerry says he doesn't actually have to make any move and that he can see Romo playing through in Big D, it's actually a legitimate assertion. He could. It might not be the smartest way to proceed, but then again, as some have iterated above, it also might not be the dumbest, given how vital high quality QBs are to a team's success and how hard they can be to find... and how often teams find themselves changing QBs due to injury or a reduction in performance--I think I counted about 1/3 of NFC teams had switched QBs since training camp, and that's just a relatively short time, testifying to, what we all know is, the precarious nature of it all.
Moreover, if reports are true that b/t Romo's fragility and his contract, no one would give up more than a conditional mid-round pick on him, the case can be made that he's worth more to the Cowboys, all told, than he is to anyone else.
The key to me is Romo himself. And if it's true, as has been reported, that a lot of his heartbreak in this is that he genuinely has a preference to stick around, then it's not as-if he's going to make a whole lot more money somewhere else. It boils down, then, to "can Romo stomach being the #2?"
I don't pretend to know, and I'm guessing he doesn't really know and won't really know until the off-season hits.
I do know that if he accepts it, then it potentially sets him up for a longer career--perhaps even an additional 2-4 years. And that might be the bottom line incentive in accepting it. The hits he doesn't take now, just make it that much more likely that he's still a marketable commodity at the end of this contract.
Can't dismiss that.
