Denver doesn't have a good OL, they have a great defense and a couple of really good receivers though. If I was Romo my top choices would be Denver or Arizona for sure.
With that said, I couldn't give two left fucks what Romo wants and I'd trade him to the highest bidder. If the compensation is relatively close I'd send him where he wants to go, but if we're talking about a 2nd vs. a 4th?
This has to be a spot where dumbass Jerry doesn't get all sentimental, although perhaps in an ironic way his love for Romo and hesitance to send him on his way could drive the price up a bit.
