Denver I could see doing it. Although Kubiak's retirement might throw a wrench into the deal. Elway has to know that defense is still dominant but the clock is counting down. Roll the dice and trade for Romo to hope he can win 1 Super Bowl with their D? Sure you gut the future a bit...but you win 2 Lombardi's in the mean time.
I'd make that bet every single time. It's too damn hard to put together a championship squad to just waste the opportunities when given. Look at Indy all those years with Manning. Brees short-lived run in NO. Marino, that one magical year in Chicago, etc, ect, etc. They have the defense to get there. Romo has a couple years left if they get an OL. It has a good chance in hell of working out. I think Romo is too brittle to make it happen but even having a year like Favre did in Minnesota? That's better than the shit they put on display this year. Or the shit they would put out next year too. They don't have a Dak on that squad. Not one they can trust for a year or two. Why waste that incredible defense?
