One thing is, unfortunately, clear - Dak's as good as he's ever going to be, and I wouldn't argue too much with those who say he's on a decline, though I don't think he is.
Having said that, teams have won SBs by just really by accident just put it all together one year, or even one post-season, as in the Giants win against the 18-0 Pats. Joe Flacco had a great post-season in "his" SB win, has done nothing of note since.
Barring a catastrophic injury or a run of low win seasons, like 4-13, 6-11 and 5-12 in a row, Dak will be our quarterback for at least another 2-3 years. People can whine, gripe, insult and bring up fanciful trade scenarios all they want, and if it makes them feel better who am I to rain on their parade? Though I have the right to comment on their posts.
Here's hoping Dak can put together that magical run, at this point while I want multiple more SB wins, I'll take the one if that's all Dallas can do for the next 26 years, or until I'm six feet under, which given my family history and current state of health is probably about 20 years away, if that. Can also hope that somehow the defense can get to Giants or Ravens level and we won't need Dak to do that much.
Regardless, tearing down Dak won't do one bit of good...
