Look, I'm a huge Romo fan. I think Romo is the better player and should be playing. I say this based off film, not personal preference. There is a lot of breakdown of this but we won't get into that. This doesn't make me anti Dak.
I think there are some anti Dak out there but I think most fans, OP included, fear Dak's rise will be accompanied with a fall equally as steep as many before him have experienced. At this point in time, I don't think you can argue that Dak could carry some of the teams Romo had to carry. Dak stepped into a perfect situation but perfect situations don't last. The fear, for me at least, is that Dak may never be the guy to lift his team(ala Alex Smith) if he has to be.
I'm a homer but sometimes you have to take the Rose colored glasses off.
