Dez has never been a good route runner, and accordingly, he has always struggled to get separation. He used to compensate for this by winning in 50/50 balls and fly routes, but that hasn't happened in the last couple seasons. That jump ball in the end zone (in the 3rd quarter I think?) was the type of catch Dez is paid to make, and instead it was batted away because he jumped for it while off balance, falling backwards. Additionally, Dak is not very good at throwing fade, slant, or go routes, which are Dez's 3 main routes. Even when Dak hits him in the hands, he muffs the catch and hands the defense an interception. Very disappointed in Dez over the past couple seasons. Dez's route running was supposed to develop as he got older, but if anything it's getting worse. It's clear that he doesn't take pride in improving his route running, because it hasn't progressed at all since his third year. He's still a valuable player no doubt, but he's no longer in the conversation as a top 5 receiver, and over the past few years, he's fallen out of the top 10 in my opinion.
