I don't enjoy Dak as a quarterback that much (there I said it), although I admit some of his runs and plays like his TD catch are exciting. I'm not sure what it is about him that I don't enjoy like I did with Romo, maybe it's simply that he's not Romo and took the place of one of my favorite players.
However, there's no way that I would ever wish injury on any player or be glad about one. We tend to view those things too casually because players get surgery and most of the time they come back. We don't experience the pain that they have to go through or even the risks (for the most part ... some here have been through similar).
Also, just because Dak is fifth on my list of favorite Cowboys quarterbacks doesn't mean I feel the need to disparage him or believe we can't win with him if the team is good enough. Just take a look at some of the past Super Bowl-winning quarterbacks. For what it's worth, I believe the right team could also win with Dalton, but we don't have close to the right team right now.
So yes, Dalton is our quarterback now ... and it means nothing without a much better defense. So I don't know what all the back and forth and fighting is about. I feel sorry for any QB who starts for this team and have for a long, long time now.
