He deserves blame. However, there were other factors. Packers got to Kyler so quickly because Josh Jones barely touched the guy he was blocking. It also seemed like Pugh got up field too late which made it difficult for Rondale to get into the spot he was supposed be at. And Kyler probably could have thrown a better pass.
The issue with Rondale is that they've kept his role limited. You almost wish Kirk was a better YAC guy so they wouldnt be so predictable with these screen passes. I'd like to see him get a few downfield targets.
The gameplan seemed like they wanted to show off their new toy in primetime and it backfired.
