Do you realize how many times Dez was targeted in last 2 games vs. how many he actually caught? WR is not a priority like the pass rush on D, but it is a position of need.
It is absolutely not a position of need. The fact that Dak targeted Dez that often does not mean the other WR were not doing their job. For starters, against the Broncos, they had an excellent plan: whereas most teams look to double Dez and take their chances with everyone else, they put their best on Dez and doubled Witten and Beasley. Dak showed his youth by constantly trying to take advantage of the single coverage. Sometimes he threw poor passes. Sometimes Dez didn't do his job. Other times, the opposing corner did his job.
That receiving core is one of the best in the league, Dak just has not been taking full advantage. Furthermore, there were several instances were Dak completely missed other open receivers while staring down the single covered Dez. See tape from confirmation...,there were several instances. Hopefully they get corrected for the upcoming game, but adding Josh Gordon in no way fixes what ailed them in this past game.
