Part of why I so rarely engage with you on this topic, is you can't keep from embellishing and twisting my actual take. I have no problem taking on the whole forum on a topic when I think I'm right, but not a lot of interest in unsaying things that I never actually said.
Team building is hugely important in the NFL. It's how good organizations actually win. Look no farther than what Roseman did for PHI last year if it's unclear somehow. My standards are to build a championship roster. I've never suggested otherwise. I believe the limitations to the current team are with the defensive personnel rather than with the HC or his staff. You clearly disagree with that, but there's no reason to pretend I'm saying something I'm not to try to make your point.
I don't think Garrett is a great head coach, and I've said this many times in many different threads. Great head coaches don't grow on trees, and if we can find one, we ought to bring one in. I think Garrett is a good fit in Dallas, though. I think he's good enough to win a championship with if the team is good enough. I think we've demonstrated a capability to build good teams in Dallas under Garrett and that's evidenced by the 12 and 13 win seasons.
I think fans with average abilities at diagnoses causes of effects are going to ***** about the HC or the QB about 90% of the time whenever expectations for the team aren't met. And I don't think that HC'ing or QB'ing is the reason is the reason why teams fail to reach their goals 90% of the time. Most of the time, I think the issue is with personnel. That's not a Dallas thing, by the way. That's an issue league-wide.
