I feel like Romo has a handful of teams on his list(which is why one day this one, next day that one) but he doesn't truly have an ideal destination yet. I expect a week or two of him making visits to a few teams.
The lady who is on the Herd with Cowherd went to a brunch that Romo was at reportedly what came straight from his mouth was that he wants to play 2-3 more years. Can Denver really offer that with Lynch sitting there? They can probably offer a one year, stop gap deal.
I think the Texans are more primed to offer multiple years(with a possibly better team)...but Denver has more organizational success than Houston.
To me, Houston seems to be a better situation for Romo but Denver has been there and Houston has not.
