The value of Zeke is seen in how teams defend the Cowboys.
Even if other RBs are on this team and they are rushing for a thousand yards, like in 2015 for example, nobody is stacking the boxes for them.
And the irony is, the Titans were average with Mariotta as QB. They added Tannehill, who was having a mediocre career, and since he's had this RG, he's been at the top of the league in QB play. This man is throwing at 70% at 22 TDs and only 7 INTs and unlike Dak, these are numbers he's doing with a mediocre PASS BLOCKING line that has given up 56 SACKS THIS YEAR.
So if anybody doesn't think the Cowboys have options in changing QBs with this RG, they are delusional.
