This team Dak has now is completely different from they 12-4 team though.
Completely? Let's compare starters:
2014 2018
O-line - Smith, Leary, Frederick, Martin, Free Smith, tbd, Frederick, Martin, Collins
Tight end - Witten and Hanna Witten and Hanna
Receivers - Dez, Williams Dez, Williams
Running back - Murray Elliot
Only left guard, right tackle and running back is different. And Collins is about as good as Free was (better if you are one of the many Free haters), Zeke is at least as good as Murray was.
And the same head coach and offensive coordinator.
Not a really different team...
