Funny, when Dez played with Dak early in Dak's career, the knock on Dez quickly became "he's a lousy route runner and can't create separation".
Which has not been, nor ever will be, said about Lamb.
For a "lousy route runner" who "couldn't create separation", I'd say Dez had some pretty good seasons catching balls from Romo.
What's more indicative to this discussion is, how did Dez perform with Romo and how did Dez perform with Dak?
There's the comparison that might shed a little more light on this.
his last 3 years with Romo as starter, Dez averaged 1312 yards per year with 14 TD a year.
His 2 years with Dak as starter, 817 yards per year and 7 TD a year.
Production literally almost cut in half.
Coincidence? Maybe. I don't think so though.
