Dak might not be able to carry the team consistently on his shoulders like Romo used to, but Dak has shown the ability to do so several times in his 2.5 year career. The 2016 playoff loss to Green Bay comes to mind. Down 18 points (21 - 3) halfway through the 2nd quarter and the Defense allowing Green Bay to constantly score at will, Dak carried the Offense the rest of the way to tie the game at 31 - 31 with only 39 seconds left in regulation. Too bad the Defense once again gave up the winning FG to Green Bay as time expired.
There have been a few more games where Dak has carried the team on his shoulders, but obviously, it has been nowhere near what franchise record holder Tony Romo accomplished during his tenure.
Dak is no Romo, just like Romo is no Dak. They both have different qualities which has shown can lead to wins. I say with a better performing Oline and some weapons at receiver & TE, Dak can lead this team to many wins year in and year out.
