You're all over the place with your discussion
First you say, NE, GB, Denver(LOL still laughing about this), and Baltimore are franchises we should mold ourselves after, but when in reality 3 of those 4 have top 10 all time great quarterbacks
Second, you try to act as though Dez is an ordinary talent and we shouldn't "overpay" him. If he's a top 3 WR, you're not overpaying him if continues to perform like he has been. YOu're just paying handsomely for that asset.
Finally, you're dispelling the idea that RBs and Murray are key compenents to winning a football game. Ask the 49ers who they would like to play? Jo Randle or Marshawn Lynch? Ask teams who they would like to face, Terrance WIlliams as the 1 or Dez Bryant as the number 1. You're right, they are not mandatory, but to imply that they don't win you football games is nonsense. YOu can win football games a multiitude of ways-defense, offensive line, great quarterback play, special teams. The passing game is another way.
I have this big problem where people want us to be like "This" team. How about we just find our own identity and stick to that, even if it implies the use of an oline, a great WR, and a good rb. It's a copy cat league, but sometimes, I feel we get too lost in that.
