I blame his terrible HC, whose approach is the more reckless the decision the better. Once in a while it works and he's a "genius" but more often the odds prevail.
Herbert will lead them to enough wins and overcome Staley's blunders just enough for him to have the Staley anchor holding him down most of his career. And Staley is a defensive specialist, who can't seem to build an elite unit with Bosa and Mack on the edges.
Can't fire a "winning" HC. The Chargers of all teams, who fired Marty after a 14-2 season, are the ones with that mentality.
Hey, good news for us though! Having Staley as the HC takes one potential contender out of the mix.
