I don't think Dallas would trade for Roethlisberger, nor do I think the Steelers would trade for Romo. In both team's eyes, neither QB is better than the other. The point is most franchises don't/won't see Romo as better than what they've got. I do think you have to view it as whether Romo's worth trading for or not. Romo's not appreciably better than anyone on that list, IMO. Which I think does put him somewhere into about the 8th-14th spot on the list of best QBs.
