So will giving big money to Zeke, Dak, and Lawrence while filling other holes for less money make the Cowboys a better team? The only way the answer is "yes" is if those contracts improve the play of Dak, Zeke, and Lawrence.
Zeke is already a top player at his position but RBs have diminishing returns - the only question is how soon. I don't believe giving Dak and Lawrence more money will improve them. At best they'll stay what they are, with a cheaper supporting cast. If someone can explain how that improves the Cowboys odds of winning a championship, I'd love to read it.
Again - there's paying guys who are the best in the NFL versus paying guys because they're the best you have at their position. The first one makes sense, the second one is reaching for a false sense of security.
"But we don't have anyone to replace them!"
Fine, then pay them like mega stars and hope for more seasons like the last one because you've pretty much made it your ceiling at that point.
