That's my biggest worry about moving on from Tony this year. That we'll end up making the playoffs, Dak will struggle and we'll end up going home when I really feel like we could compete for a SB this year.
I'm not saying I'm against the move to stay with Dak. Not at all. I get it. However, if the best QB on the team is on the bench, then you're not really giving yourself the best shot at a SB in a year where it seems like we could actually win one.
I hear you but it's the line you've got tow; the team is playing like a well-oiled machine right now and you don't want to muck it up by changing out a key cog (i.e. Dak).
Beyond that, let's think about it. This is almost a lose-lose situation for Romo. He comes in and struggles and fans will berate the franchise and call for the quick hook on Romo. If Romo comes in and we continue to win but lose in the playoffs, the masses will lament "why'd we take Dak out?!?!"
IMO, the only way this plays out in Romo's favor from a perception standpoint is if Dak gets hurt and Romo comes in. Romo would then be benefited by the fact there was no alternative and that he was put in as a necessity, rather than a coaching decision to replace Dak.
