No, it is not the same thing.
Dak walked into the best OL and RG in football. When teams say on Cole Beasley’s routes the next year, he completely sucked. Dallas still had the same talent as 13-3. He was the absolute weak link.
2017 was considered a disaster for Dak. 2018 he was setting Quincy Carter records in futility, despite that OL and RG. He sucked and continued to suck in zone coverage and still does and so on.
Herbert is in his second year starting and is in no way considered the weak link of this football team. And if we are going by players, the whole Chargers team was injured. And Herbert was not the weak link anyways.
And Staley is absolute garbage as a play caller. Moore runs light years around this guy.
